Since his first day in office, Donald Trump has not been an ordinary president, having surprised Americans and the world many times with unexpected decisions.

US President Donald Trump is on his way out of the White House, but he still has 20 days in his pocket, and he still enjoys all the constitutional powers granted to him as President of the United States and commander-in-chief of its armed forces.

Experts and commentators compete to anticipate the surprises that Trump may bring before the end of his term in mid-January 20, and it makes it difficult for these people to have no restrictions before Trump, as he will not have to confront the voters soon, and the constitution does not limit his role after his defeat in The election.

Trump can surprise the Americans and the world through 3 mechanisms, which are:

First: the removal of officials

During recent weeks, a number of administration officials begin to present their resignations and search for alternative opportunities, but traditionally this phenomenon does not extend to ministerial positions and other high-ranking positions in the administration.

Trump has already fired the Secretary of Defense and a number of senior Pentagon officials, as well as the cybersecurity official at the Department of Homeland Security.

He is expected to dismiss Chris Ray, director of the FBI, Gina Haspel, Director of the Central Intelligence Agency, and Bill Barr, Minister of Justice, for failing to confirm election fraud, according to what Trump sees.

The Associated Press quoted US Attorney General William Barr that his department did not discover widespread fraud that could change the election result, which prompted Trump's legal team to respond and confirm that the department's investigations were not serious.

When asked whether he would fire Barr, Trump replied, "You will know in a matter of weeks."

Second: Issue laws by executive orders

Since the start of his presidency 4 years ago, Trump has resorted to implementing his political agenda by resorting to the president's right to issue executive orders in the absence of Congressional support, and in some cases he succeeded in that, as the Supreme Court ultimately upheld the ban on citizens of several Muslim countries from entering the United States.

In other cases, the Supreme Court thwarted Trump's orders, refusing to dismantle the Immigration Program for Immigrant Children (DACA), before a federal judge decided to suspend Trump's executive orders.

Trump may again try to dismantle the same program before leaving office, as the Supreme Court has left the door open for the administration to issue a new order using appropriate administrative procedures.

Trump may issue executive orders related to health care law, environmental protection programs and immigration policies.

Gregory Cougar - the dean of the political science department at the University of Miami, Florida - spoke to Al Jazeera Net about what Trump might offer in his last weeks.

Cougar indicated that Trump may aim to change some regulations and procedures that impede some policies, or liberalize areas overseen by the government, and may allow "oil and gas exploration in areas that are important for preserving environmental diversity, especially in northern Alaska," for example, according to For Cougars.

It is worth noting that the new president, Joe Biden, has the right to revoke the executive orders that Trump takes when his term begins on January 20.

Third: Exercising his right to issue a pardon

Trump's issuance of a series of exemptions in recent weeks and until his last day will not be surprising, as previous presidents have issued waivers during the last days of their term, including Bill Clinton, who on his last day pardoned his brother Roger Clinton and the fugitive billionaire financier Mark Rich.

Who will be pardoned by Trump?

After Trump has pardoned 45 people so far, the last of whom was General Michael Flynn on Thanksgiving Eve, Trump may pardon others convicted by Detective Robert Mueller's team, including Paul Manafort, former campaign director for President Donald Trump and George Papadopoulos, a former campaign aide.

Trump could also preemptively pardon members of his family and others in the Trump Organization.

New York state attorneys are reported to be investigating Trump's organization into possible fraud, but the presidential pardon only covers federal crimes and not state crimes.

Trump may issue a preemptive pardon to Steve Bannon, his former adviser who has been charged with several charges of fraud.

The most important question remains regarding the possibility that Trump may issue a preemptive presidential pardon for himself.

Cougar asserts that Trump "retains presidential power until January 20, and there is still a lot he can take, and one of the unrestricted forces is the ability of presidents to pardon people who have been convicted of violating federal crimes or who have only been accused of doing so." Trump can pardon members of his immediate family and those close to him such as Paul Manafort and Rudy Giuliani, and he may even try to pardon himself, although it is not clear that this is constitutionally possible. "

Does Trump surprise us by pardoning himself?

It is not known conclusively whether presidential self-pardon is legal, as he has never before had this experience.

The constitution places no explicit restriction on the power to pardon, and legal scholars disagree on this issue, and if Trump pardoned himself, the Supreme Court could provide a final answer.

Some experts argue that Trump has ignored the rule of law, norms and political traditions for more than 46 months, and has nothing to lose after having already lost the presidential election.

All we have to do now is wait to see what Trump has in store for America and the world, from this moment until January 20.
