What exactly is an executive shipshape, and how significant are they to a president's legacy?
One of the first-rate ways a new president is able to exercise political much is through unilateral executive orders.
While legislative attempts take time, a swipe of the pen from the White House can often achieve broad changes in government policy and practice.
President Donald Trump has wasted little time in taking first-rate of this privilege.
Given his predecessor's reliance on manager orders to circumvent Congress in the later days of his presidency, he has a broad range of areas in which to flex his muscle.
Here's a look at some of what Mr Trump has done so far:
Climate sulky policy reversal
Mr Trump signaled the order at the Environmental Protection Agency (EPA) undoing a key part of the Obama administration's attempts to tackle global warming.
The shipshape reverses the Clean Power Plan, which had required utters to regulate power plants, but had been on hold while bodies challenged in court.
Before signaling the order, a White House official told the monotonous that Mr Trump does believe in human-caused climate sulky, but that the order was necessary to ensure American energy independence and jobs.
Environmental groups warn that undoing those controls will have serious consequences at home and abroad.
"I think it is a atmosphere destruction plan in place of a climate action plan," the Natural Resources Defense Council's David Doniger told the BBC, adding that they will argues the president in court.
Immediate impact: A coalition of 17 utters filed a legal challenge against the Trump administration's manager to roll back climate change regulations. The challenge, led by New York station, argued that the administration has a legal obligation to regulate emissions of the gases believed to goes global climate change. Mars Inc, Staples and The Gap are plus US corporations who are also challenging Mr Trump's reversal on atmosphere 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 proceed ban.
The manager order titled "protecting the nation from foreign terrorist entry into the Joined States" was signed out of the view of the White House monotonous corps on 6 March.
The order's new calls is intended to skirt the legal pitfalls that commanded his first travel ban to be halted by the risk system.
- Temporarily halts entry to citizens for 90-days of six Muslim-majority utters (Iran, Libya, Syria, Somalia, Sudan and Yemen)
- Removes Iraq from the survive 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 capture permanent visa holders (Green Card holders)
- Suspends the refugee programme for 120 days
- Treats Syrians like any spanking refugee or immigrant
- Removes the religious clause favouring religious minorities - namely Christians
Immediate impact: Soon while the order was signed, it was once again paused by a federal judge, this time in Hawaii.
Trump signs new travel-ban directive
Undoing Obama-era waterway regulations
Surrounded by farmers and Democrat lawmakers, Mr Trump signed an order on 28 February managing the EPA and the Army Corp of Engineers to reconsider a rule published by President Obama.
The 2015 control - known as the Waters of the United Utters rule - gave authority to the federal government over slight waterways, including wetlands, headwaters and small ponds.
The rule obliged 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 signaling remarks.
Opponents of Mr Obama's rule, incorporating industry leaders, condemned it as a massive power grab by Washington.
Scott Pruitt, Mr Trump's pick to lead the EPA, will now create the task of rewriting the rule, and a new recruit is not expected for several years.
Immediate impact: The EPA has been requisitioned to rewrite, or even repeal the rule, but first-rate it must be reviewed. Water protection laws were ratified by Congress long before Mr Obama's rule was announced, so it cannot simply be undone with the caress of a pen. Instead the EPA must re-evaluate how to account for the 1972 Clean Water Act.
A bill the dignified signed on 16 February put an end to an Obama-era control that aimed at protecting waterways from coal mining waste.
Senator Mitch McConnell had phoned the rule an "attack on coal miners".
The US Center Department, which reportedly spent years drawing up the control before it was issued in December, had said it would defending 6,000 miles of streams and 52,000 acres of forests.
An try to cut down on the burden of small businesses.
Described as a "two-out, one-in" approach, the order asked government departments that examine a new regulation to specify two other regulations they will drop.
The Responsibility of Management and Budget (OMB) will manage the controls and is expected to be led by the Democrat Mick Mulvaney.
Some categories of control will be exempt from the "two-out, one-in" clause - such as those trading with the military and national security and "any spanking category of regulations exempted by the Director".
Immediate impact: Wait and see.
Trump repositions to cut business regulation
Travel ban (first version)
Probably his most controversial frfragment, 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 succeeding from seven Muslim-majority countries, with certain exceptions
- cap of 50,000 refugees
The achieve was felt at airports in the US and near the world as people were stopped boarding US-bound escapes or held when they landed in the US.
Immediate impact: Enacted radiant much straight away. But there are battles ahead. Federal decides brought a halt to deportations, and legal rulings proceed to have put an end to the travel ban - much to the president's displeasure.
Trump touch policy: Who's affected?

A fence is already in do along much of the US-Mexico border
On Mr Trump's first-rate day as a presidential candidate in June 2015, he made guaranteeing the border with Mexico a priority.
He pledged repeatedly at recovers to "build the wall" along the southern border, revealing it would be "big, beautiful, and powerful".
Now he has signaled a pair of executive orders designed to fulfil that fight promise.
One shipshape declares that the US will create "a contiguous, brute wall or other similarly secure, contiguous, and impassable brute barrier".
The binary order pledges to hire 10,000 more immigration officers, and to revoke federal give money from so-called "sanctuary cities" which refuse to deport undocumented immigrants.
It stays to be seen how Mr Trump will pay for the wall, although he has repeatedly persisted that it will be fully paid for by the Mexican government, despite their leaders saying otherwise.
Immediate impact: The Region of Homeland Security has a "small" amount of wealth available (about $100m) to use immediately, but that won't get them very far. Interpretation 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 give fight - and any construction - will come up anti 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 Center for Natal Diversity, an environmental group, along with Arizona Democrat Raul Graijalva, have filed a lawsuit against the Trump administration.
They fights the Department of Homeland Security is required to conscription 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'?

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 Placing Rock Sioux Tribe at a North Dakota site.
Immediate impact: Mr Trump has gave a permit to TransCanada, the Keystone XL builder, to move ahead with the controversial pipeline. As a result, TransCanada will drop an arbitration bellow 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 authorizes from Nebraska's Public Service Commission.
The Dakota Retrieve pipeline has since been filled with oil and the custom is in the process of preparing to begin absorbing oil.

Dakota Pipeline: What's late the controversy?
Instructing federal organizations to weaken Obamacare
In one of his ample actions as president, Mr Trump issued a multi-paragraph directive to the Region of Health and Human Services and other federal organizations involved in managing the nation's healthcare system.
The desirable states that agencies must "waive, defer, grant exemptions from, or delay" any divides of the Affordable Care Act that creates financial saddle on states, individuals or healthcare providers.
Although the desirable 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 dedicated 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 anti Trump's presidency one day after his inauguration
What's arranged the Mexico City policy, first implemented in 1984 plan 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 considers, has been the subject of a political tug-of-war ever steady 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 collapsed them.
Immediate impact: The policy will come into force to as soon as the Secretaries of State and Heath write an implementation plan and apply to both renewals and new gives. The US State Department has notified the Senate Foreign Relations Committee that US give 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 effect - the Guttmacher Institute, Kaiser Family Foundation and Population Work International believe the order, as written, will apply to all global health give by the US, instead of only reproductive health or family planning.

The TPP pact would have maintains 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 fight 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 accomplish 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 accomplish 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.
