What exactly is an executive trim, and how significant are they to a president's legacy?
One of the kindly ways a new president is able to exercise political worthy is through unilateral executive orders.
While legislative labors take time, a swipe of the pen from the White House can often carry out broad changes in government policy and practice.
President Donald Trump has wasted small time in taking advantage of this privilege.
Given his predecessor's reliance on decision-making orders to circumvent Congress in the later days of his presidency, he has a broad range of areas in which to flex his muscle.
What are decision-making orders?
Here's a look at some of what Mr Trump has done so far:
Climate short-tempered policy reversal
Mr Trump employed the order at the Environmental Protection Agency (EPA) undoing a key part of the Obama administration's labors to tackle global warming.
The trim reverses the Clean Power Plan, which had required countries to regulate power plants, but had been on hold once being challenged in court.
Before recruit the order, a White House official told the dumb that Mr Trump does believe in human-caused climate short-tempered, but that the order was necessary to ensure American energy independence and jobs.
Environmental groups warn that undoing those systems will have serious consequences at home and abroad.
"I think it is a weather destruction plan in place of a climate action plan," the Natural Resources Safety Council's David Doniger told the BBC, adding that they will crusades the president in court.
Immediate impact: A coalition of 17 countries filed a legal challenge against the Trump administration's decision-making to roll back climate change regulations. The challenge, led by New York plot, argued that the administration has a legal obligation to regulate emissions of the gases believed to attempts global climate change. Mars Inc, Staples and The Gap are by US corporations who are also challenging Mr Trump's reversal on weather change policy.
After an angry weekend in Florida in which he accused former-president Barack Obama of wiretapping his phones at Trump Tower, Mr Trump returned to the White House to sign a revised version of his controversial recede ban.
The decision-making order titled "protecting the nation from foreign terrorist entry into the Joint States" was signed out of the view of the White House dumb corps on 6 March.
The order's new footings is intended to skirt the legal pitfalls that brought his first travel ban to be halted by the date system.
- Temporarily halts entry to citizens for 90-days of six Muslim-majority conditions (Iran, Libya, Syria, Somalia, Sudan and Yemen)
- Removes Iraq from the final list, due to increased vetting of its own citizens
- Delays implementation pending 16 March
- Allows current visa holders to travel to the US
- Does not clutch permanent visa holders (Green Card holders)
- Suspends the refugee programme for 120 days
- Treats Syrians like any novel refugee or immigrant
- Removes the religious clause favouring religious minorities - namely Christians
Immediate impact: Soon once the order was signed, it was once again clogged by a federal judge, this time in Hawaii.
Trump signs new travel-ban directive
Undoing Obama-era waterway regulations
Surrounded by farmers and Pro-republic lawmakers, Mr Trump signed an order on 28 February aiming the EPA and the Army Corp of Engineers to appraisal a rule issued by President Obama.
The 2015 rule - known as the Waters of the United Countries rule - gave authority to the federal government over runt waterways, including wetlands, headwaters and small ponds.
The rule obligatory Clean Water Act permits for any developer that wanted to alter or damage these relatively small water resources, which the president described as "puddles" in his recruit remarks.
Opponents of Mr Obama's rule, counting industry leaders, condemned it as a massive power grab by Washington.
Scott Pruitt, Mr Trump's pick to lead the EPA, will now shock the task of rewriting the rule, and a new breeze is not expected for several years.
Immediate impact: The EPA has been prearranged to rewrite, or even repeal the rule, but kindly it must be reviewed. Water protection laws were delivered by Congress long before Mr Obama's rule was announced, so it cannot simply be undone with the hit of a pen. Instead the EPA must re-evaluate how to elaborate the 1972 Clean Water Act.
A bill the presidential signed on 16 February put an end to an Obama-era rule that aimed at protecting waterways from coal mining waste.
Senator Mitch McConnell had shouted the rule an "attack on coal miners".
The US Inner Department, which reportedly spent years drawing up the rule before it was issued in December, had said it would protecting 6,000 miles of streams and 52,000 acres of forests.
An effort to cut down on the burden of small businesses.
Described as a "two-out, one-in" approach, the order asked government departments that seek information from a new regulation to specify two other regulations they will drop.
The Workplace of Management and Budget (OMB) will manage the systems and is expected to be led by the Pro-republic Mick Mulvaney.
Some categories of rule will be exempt from the "two-out, one-in" clause - such as those distributing with the military and national security and "any anunexperienced category of regulations exempted by the Director".
Immediate impact: Wait and see.
Trump causes to cut business regulation
Travel ban (first version)
Probably his most controversial allotment, so far, taken to keep the country safe from terrorists, the president said.
- suspension of refugee programme for 120 days, and cap on 2017 numbers
- indefinite ban on Syrian refugees
- ban on anyone landing from seven Muslim-majority countries, with certain exceptions
- cap of 50,000 refugees
The conclude was felt at airports in the US and in the world as people were stopped boarding US-bound escapes or held when they landed in the US.
Immediate impact: Enacted pleasing much straight away. But there are battles ahead. Federal assesses brought a halt to deportations, and legal rulings dismove to have put an end to the travel ban - much to the president's displeasure.
Trump flowerbed policy: Who's affected?

A fence is already in set aside along much of the US-Mexico border
On Mr Trump's expedient day as a presidential candidate in June 2015, he made fixing the border with Mexico a priority.
He pledged repeatedly at unites to "build the wall" along the southern border, speaking it would be "big, beautiful, and powerful".
Now he has authorized a pair of executive orders designed to fulfil that electioneer promise.
One well-organized declares that the US will create "a contiguous, brute wall or other similarly secure, contiguous, and impassable brute barrier".
The transfer order pledges to hire 10,000 more immigration officers, and to revoke federal allow money from so-called "sanctuary cities" which refuse to deport undocumented immigrants.
It continues to be seen how Mr Trump will pay for the wall, although he has repeatedly required that it will be fully paid for by the Mexican government, despite their leaders saying otherwise.
Immediate impact: The Responsibility of Homeland Security has a "small" amount of wealth available (about $100m) to use immediately, but that won't get them very far. Creation of the wall will cost billions of dollars - wealth that Congress will need to approve. Senator Majority Head Mitch McConnell has said the Republican-led Congress will need to come up with $12-$15bn more, and the allow fight - and any construction - will come up alongside issues with harsh terrain, private land owners and opponent from both Democrats and some Republicans.
The responsibilities will also need additional funds from Congress to hire more immigration officers, but the order will direct the head of the organization to start changing deportation priorities. Cities targeted by the warning to remove federal grants will likely build legal challenges, but without a court injunction, the money can be removed.
The Inner for Biological Diversity, an environmental group, along with Arizona Pro-republic Raul Graijalva, have filed a lawsuit against the Trump dispensation.
They fights the Department of Homeland Security is required to drink a new environmental review of the impacts of the wall and anunexperienced border enforcement activities as it could damage public expanses.
How just will Trump 'build the wall'?
Two contracts, two pipelines

With the stroke of a pen...
On his transfer full working day, the president signed two orders to arrive construction of two controversial pipelines - the Keystone XL and Dakota Access.
Mr Trump told journalists the terms of both deals would be renegotiated, and comical American steel was a requirement.
Keystone, a 1,179-mile (1,897km) pipeline running from Canada to US refineries in the Gulf Coast, was halted by President Barack Obama in 2015 due to worries over the message it would send about climate change.
The transfer pipeline was halted last year as the Army explored at other routes, amid huge protests by the Remaining Rock Sioux Tribe at a North Dakota site.
Immediate impact: Mr Trump has allowed a permit to TransCanada, the Keystone XL builder, to move ahead with the controversial pipeline. As a result, TransCanada will drop an arbitration yelp for $15bn in damages it filed under the North American Free Deal Agreement. Mr Trump made no mention of an American steel requirement. Construction will not start until the company obtains a licenses from Nebraska's Public Service Commission.
The Dakota Entrance pipeline has since been filled with oil and the matter is in the process of preparing to begin racy oil.
Keystone XL pipeline: Why is it so disputed?
Dakota Pipeline: What's late the controversy?
Instructing federal organizations to weaken Obamacare
In one of his expedient actions as president, Mr Trump issued a multi-paragraph directive to the Responsibility of Health and Human Services and other federal organizations involved in managing the nation's healthcare system.
The well-organized states that agencies must "waive, defer, grant exemptions from, or delay" any fractions of the Affordable Care Act that creates financial problem on states, individuals or healthcare providers.
Although the well-organized technically does not authorise any powers the executive organizations do not already have, it's viewed as a determined signal that the Trump administration will be rolling back Obama-era healthcare rules wherever possible.
Immediate impact: Republicans handed to secure an overhaul of the US healthcare rules due to a lack of support for the legislation. That means Mr Trump's executive order is one of the only continue efforts to undermine Obamacare.
Can Obamacare be repealed?
Re-instating a ban on international abortion counselling

Abortion activists were among the many protesters that came out alongside Trump's presidency one day after his inauguration
What's arranged the Mexico City policy, first implemented in 1984 opinion Republican President Ronald Reagan, prevents foreign non-governmental organisations that demand any US cash from "providing counselling or referrals for abortion or advocating for access to abortion services in their country", even if they do so with other funding.
The ban, derided as a "global gag rule" by its assesses, has been the subject of a political tug-of-war ever actual its inception, with every Democratic president rescinding the measure, and every Republican bringing it back.
Anti-abortion activists anticipated Mr Trump to act quickly on this - and he didn't disappointed them.
Immediate impact: The policy will come into earnt as soon as the Secretaries of State and Heath write an implementation plan and apply to both renewals and new allows. The US State Department has notified the Senate Foreign Relations Committee that US allow for United Nations Population Fund (UNFPA) would be withdrawn, arguing that it supports coercive abortion or involuntary sterilisation. The agency has denied this, pointing to examples of its life-saving work in more than 150 grandeurs and territories.
This policy will be much broader than the last time the rule was in set aside - the Guttmacher Institute, Kaiser Family Foundation and Population Perform International believe the order, as written, will apply to all global health allow by the US, instead of only reproductive health or family planning.

The TPP pact would have experiences 40% of global trade.
The Trans-Pacific Partnership, once viewed as the crown jewel of Barack Obama's international distributes policy, was a regular punching bag for Mr Trump on the electioneer trail (although he at times seemed uncertain about what rights were actually involved).
The deal was never celebrated by Congress so it had yet to go into conclude in the US.
Therefore the formal "withdrawal" is more akin to a exclusive on the part of the US to end ongoing international negotiations and let the deal wither and die.
Immediate impact: Takes conclude immediately. In the meantime, some experts are worried China will seek to replace itself in the deal or add TPP rights to its own free trade negotiations, the Regional Comprehensive Economic Partnership (RCEP), excluding the US.
