What exactly is an executive smart, and how significant are they to a president's legacy?
One of the obedient ways a new president is able to exercise political remarkable is through unilateral executive orders.
While legislative exertions take time, a swipe of the pen from the White House can often conclude broad changes in government policy and practice.
President Donald Trump has wasted minor time in taking advantage of this privilege.
Given his predecessor's reliance on exclusive 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 exclusive orders?
Here's a look at some of what Mr Trump has done so far:
Climate sullen policy reversal
Mr Trump authorized the order at the Environmental Protection Agency (EPA) undoing a key part of the Obama administration's exertions to tackle global warming.
The smart reverses the Clean Power Plan, which had required messes to regulate power plants, but had been on hold at what time being challenged in court.
Before hiring the order, a White House official told the lifeless that Mr Trump does believe in human-caused climate sullen, 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 Confidence Council's David Doniger told the BBC, adding that they will disputes the president in court.
Immediate impact: A coalition of 17 messes filed a legal challenge against the Trump administration's decision-making to roll back climate change regulations. The challenge, led by New York situation, argued that the administration has a legal obligation to regulate emissions of the gases believed to shifts 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 fade ban.
The exclusive order titled "protecting the nation from foreign terrorist entry into the Married States" was signed out of the view of the White House lifeless corps on 6 March.
The order's new conditions is intended to skirt the legal pitfalls that transported his first travel ban to be halted by the date system.
- Temporarily halts entry to citizens for 90-days of six Muslim-majority messes (Iran, Libya, Syria, Somalia, Sudan and Yemen)
- Removes Iraq from the remaining 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 latest refugee or immigrant
- Removes the religious clause favouring religious minorities - namely Christians
Immediate impact: Soon once the order was signed, it was once again discontinued 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 journal 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 friendly it must be reviewed. Water protection laws were happened 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 requested 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 commerce with the military and national security and "any novel category of regulations exempted by the Director".
Immediate impact: Wait and see.
Trump shifts to cut business regulation
Travel ban (first version)
Probably his most controversial share, 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 reaching from seven Muslim-majority countries, with certain exceptions
- cap of 50,000 refugees
The enact was felt at airports in the US and about the world as people were stopped boarding US-bound trips or held when they landed in the US.
Immediate impact: Enacted magnificent much straight away. But there are battles ahead. Federal moderators brought a halt to deportations, and legal rulings depart to have put an end to the travel ban - much to the president's displeasure.

A fence is already in establish along much of the US-Mexico border
On Mr Trump's friendly day as a presidential candidate in June 2015, he made obtaining the border with Mexico a priority.
He pledged repeatedly at meetings to "build the wall" along the southern border, proverb it would be "big, beautiful, and powerful".
Now he has employed a pair of executive orders designed to fulfil that movement promise.
One trim declares that the US will create "a contiguous, substantial wall or other similarly secure, contiguous, and impassable substantial barrier".
The instant order pledges to hire 10,000 more immigration officers, and to revoke federal funding money from so-called "sanctuary cities" which refuse to deport undocumented immigrants.
It corpses to be seen how Mr Trump will pay for the wall, although he has repeatedly maintained that it will be fully paid for by the Mexican government, despite their leaders saying otherwise.
Immediate impact: The Section of Homeland Security has a "small" amount of cash available (about $100m) to use immediately, but that won't get them very far. Building of the wall will cost billions of dollars - cash that Congress will need to approve. Senator Majority Front-runner Mitch McConnell has said the Republican-led Congress will need to come up with $12-$15bn more, and the grant fight - and any construction - will come up in contradiction of issues with harsh terrain, private land owners and antagonism from both Democrats and some Republicans.
The sections will also need additional funds from Congress to hire more immigration officers, but the order will direct the head of the activity to start changing deportation priorities. Cities targeted by the danger to remove federal grants will likely build legal challenges, but without a court injunction, the money can be removed.
The Interior for Biological Diversity, an environmental group, along with Arizona Republican Raul Graijalva, have filed a lawsuit against the Trump management.
They crusades the Department of Homeland Security is required to breeze a new environmental review of the impacts of the wall and novel border enforcement activities as it could damage public acres.
How precisely will Trump 'build the wall'?
Two stabilities, two pipelines

With the stroke of a pen...
On his instant full working day, the president signed two orders to approach construction of two controversial pipelines - the Keystone XL and Dakota Access.
Mr Trump told journalists the terms of both deals would be renegotiated, and amdroll 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 affairs over the message it would send about climate change.
The instant pipeline was halted last year as the Army examined at other routes, amid huge protests by the Status Rock Sioux Tribe at a North Dakota site.
Immediate impact: Mr Trump has decided a permit to TransCanada, the Keystone XL builder, to move onward with the controversial pipeline. As a result, TransCanada will drop an arbitration issue for $15bn in damages it filed under the North American Free Commerce Agreement. Mr Trump made no mention of an American steel requirement. Construction will not start until the company obtains a permits from Nebraska's Public Service Commission.
The Dakota Admission pipeline has since been filled with oil and the commercial is in the process of preparing to begin inviting oil.
Keystone XL pipeline: Why is it so disputed?
Dakota Pipeline: What's gradual the controversy?
Instructing federal activities to weaken Obamacare
In one of his friendly actions as president, Mr Trump issued a multi-paragraph directive to the Section of Health and Human Services and other federal activities involved in managing the nation's healthcare system.
The trim states that agencies must "waive, defer, grant exemptions from, or delay" any helpings of the Affordable Care Act that creates financial load on states, individuals or healthcare providers.
Although the trim technically does not authorise any powers the executive activities do not already have, it's viewed as a sure signal that the Trump administration will be rolling back Obama-era healthcare systems wherever possible.
Immediate impact: Republicans imparted 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 previous 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 in contradiction of Trump's presidency one day after his inauguration
What's requested the Mexico City policy, first implemented in 1984 concept Republican President Ronald Reagan, prevents foreign non-governmental organisations that assertion 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 moderators, has been the subject of a political tug-of-war ever precise its inception, with every Democratic president rescinding the measure, and every Republican bringing it back.
Anti-abortion activists imagined Mr Trump to act quickly on this - and he didn't nosedived them.
Immediate impact: The policy will come into caused as soon as the Secretaries of State and Heath write an implementation plan and apply to both renewals and new scholarships. The US State Department has notified the Senate Foreign Relations Committee that US grant 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 conditions and territories.
This policy will be much broader than the last time the rule was in establish - the Guttmacher Institute, Kaiser Family Foundation and Population Law International believe the order, as written, will apply to all global health grant 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.
