As Trump sat in the Oval Office and signed order after order, lawsuits began rolling in thick and fast.
Though holding office gives Trump power, that power isn’t unlimited.
He may still face some big hurdles – one being Congress.
Congress wields a considerable amount of power and can step in to either review or block an executive order from becoming law.
Another challenge Trump will face is the courts, which can find an executive order “unconstitutional”.
Metzger said the Supreme Court could find a president had overstepped his executive authority.
It’s happened in the past.
President Harry S. Truman signed an executive order to seize control of the steel industry in 1952, but after companies sued, the Supreme Court later decided he lacked the authority and reversed this decision.
Here are all the executive orders signed by Trump which may be challenged.
Ending automatic birthright citizenship
A number of advocates swiftly sued the president over his executive order ending automatic US citizenship for children born to immigrants without legal status.
The American Civil Liberties Union (ACLU) is among those who argue Trump is unfairly denying a right which is enshrined in the 14th Amendment in the US Constitution.
Trump’s order, if enforced, is a stark revision of the 14th Amendment in the US Constitution.

“Birthright citizenship embodies America’s most fundamental promise: that all children born on our soil begin life as full and equal members of our national community, regardless of their parents’ origins, status, or circumstances,” according to the complaint filed in the state of New Hampshire.
“This principle has enabled generations of children to pursue their dreams and build a stronger America.”
Only recognising two genders
Trump signed an order to remove “gender ideology guidance” from any US federal government communication or policies, making it an official decree that there are only two genders: male and female.
“Agencies will cease pretending that men can be women and women can be men when enforcing laws that protect against sex discrimination,” the order states.
It marks a reversal of a Biden administration action to recognise all gender identities.
There have already been some legal challenges relating to this executive action.
The Human Rights Campaign said it will “fight back” against the “harmful provisions” outlined in the executive order.
Ordering all federal employees to work from home
Trump ordered all federal workers in the US to return to the office full-time.
“Heads of all departments and agencies in the executive branch of Government shall, as soon as practicable, take all necessary steps to terminate remote work arrangements,” the White House said in a statement.
This could be a tough one to enforce, as around 26 per cent of federal workers are unionised and are covered by remote or hybrid work agreements, Reuters reports.
Non-union federal workers can be ordered back to the office but need a 30-day written notice with a reason and an opportunity to respond.
Labelling drug cartels ‘foreign terrorist organisations’
It could result in US citizens or US-owned businesses prosecuted and may impact relations with Mexico.
Mike Vigil, former head of the US Drug Enforcement Administration’s foreign operations, told AP he expected terrorism designation to have “very little impact on day-to-day operations for cartels”.
“This was because many of the same anti-terrorism powers American authorities would be granted are already employ in counter-narcotics efforts in Mexico”.
