It wasn’t too long ago that Donald Trump derided presidential executive orders as “power grabs” and a “basic disaster.”

He’s switched sides in a big way: In each year of his presidency, he has issued more executive orders than did former President Barack Obama during the same time span. He surpassed Mr Obama’s third-year total just recently.

Back in 2012, Mr Trump had tweeted: “Why Is @BarackObama constantly issuing executive orders that are major power grabs of authority?”

That criticism continued once he entered the presidential race.

“The country wasn’t based on executive orders,” Trump said at a South Carolina campaign stop in February 2016. “Right now, Obama goes around signing executive orders. He can’t even get along with the Democrats, and he goes around signing all these executive orders. It’s a basic disaster. You can’t do it.”

But Mr Trump appears to have learned what his predecessors discovered as well: It’s easier and often more satisfying to get things done through administrative action than to get Congress to go along, said Andrew Rudalevige, a professor at Bowdoin College who studies the history and effectiveness of presidential executive actions.

“Most candidates don’t realise the utility of executive actions while campaigning,” Mr Rudalevige said. “When they become president, they quickly gain an appreciation of how difficult it is to get things done in government.”

he White House declined to comment on Mr Trump’s use of executive orders. He surpassed Mr Obama’s third-year total when, in the last two weeks, he issued five executive orders relating to Medicare, government transparency, federal spending and imposing sanctions on Turkish officials.

An executive order can have the same effect as a federal law — but its impact can be fleeting. Congress can pass a new law to override an executive order and future presidents can undo them.

Every president since George Washington has used the executive order power, according to the National Constitution Centre, and some of those orders played a critical role in American history. President Franklin Roosevelt established internment camps during World War II. President Harry Truman mandated equal treatment of all members of the armed forces through executive orders. And President Dwight Eisenhower used an executive order to enforce school desegregation in Little Rock.

When Mr Obama became frustrated with how difficult it was to push legislation through Congress, he warned Republicans he would take executive action when he considered it necessary.

He famously declared in 2014: “We’re not just going to be waiting for legislation in order to make sure that we’re providing Americans the kind of help they need. I’ve got a pen, and I’ve got a phone.”

Few candidates for office have placed so much emphasis on criticising a predecessor’s executive orders as Mr Trump did. He reasoned that Mr Obama’s use of executive orders made him look like a weak negotiator. But Mr Trump himself has had little success with Congress in that regard. His biggest legislative achievement so far, a $1.5 trillion (£1.15 trillion) tax cut, failed to gain one Democratic vote.

Mr Trump has so far issued 130 executive orders. By comparison, Obama issued 108 in his first three years.

Still, Mr Rudalevige says that comparing executive orders from one president to the next can provide a misleading snapshot of a president’s propensity for taking executive action. That’s because presidents also use memoranda and proclamations to achieve policy goals or to get the message out about their priorities. One president’s executive order might be another’s memoranda, or phone call even.

Mr Obama relied on memoranda and proclamations for some of his most disputed executive actions, so just counting his executive orders understates his efforts to take action without Congress passing a bill.

For example, protections for young immigrants brought into the country illegally as children came about through a Department of Homeland Security memorandum. That effort allowed eligible individuals to request temporary relief from deportation and apply for authorisation to work in the US.

Mr Obama took the action after Congress had declined to pass the Dream Act, legislation that would have helped a similar group of migrants. Republicans argued Mr Obama overstepped his constitutional authority. In November, the US Supreme Court will hear arguments over the Trump administration’s plan to end the program, which has protected roughly 700,000 young immigrants from deportation. Lower courts have so far blocked the administration from ending the program.

Mr Obama also issued proclamations to declare new national monuments in Utah and Nevada in his final days in office. In all, he issued 34 monument proclamations, including designating 29 new monuments and enlargement of five existing monuments as he brandished his conservation legacy. Some of the largest monument designations were heavily criticised by state and local officials.

Mr Rudalevige said that Mr Trump appears to favour the pomp and ceremony that often comes with an executive order. He routinely makes a speech, administration officials and potentially affected Americans get to thank him for taking action and Mr Trump often signs the order before the cameras, holding it up in the air for photographers to capture the moment.

“I think it fits his personality,” Mr Rudalevige said.
