President Trump has suggested to aides he wants to pardon himself in the final days of his presidency, according to two people with knowledge of the discussions.

The New York Times described it as a move that would mark one of the most extraordinary and untested uses of presidential power in American history.

In several conversations since Election Day, Mr. Trump has told advisers that he is considering giving himself a pardon and, in other instances, asked whether he should and what the effect would be on him legally and politically, according to the two people.

According to the New York Times, it was not clear whether he had broached the topic since he incited his supporters on Wednesday to march on the Capitol where some stormed the building in a mob attack.

Mr. Trump has shown signs that his level of interest in pardoning himself goes beyond idle musings.

He has long maintained he has the power to pardon himself, and his polling of aides’ views is typically a sign that he is preparing to follow through on his aims.

President Trump has also become increasingly convinced that his perceived enemies will use the levers of law enforcement to target him after he leaves office.

No president has pardoned himself, so the legitimacy of prospective self-clemency has never been tested in the justice system, and legal scholars are divided about whether the courts would recognize it.

But they agree a presidential self-pardon could create a dangerous new precedent for presidents to unilaterally declare they are above the law and to insulate themselves from being held accountable for any crimes they committed in office.

Mr. Trump has considered a range of pre-emptive pardons for family, including his three oldest children — Donald Trump Jr., Eric Trump, and Ivanka Trump — for Ms. Trump’s husband, the senior White House adviser Jared Kushner, and for close associates like the president’s personal lawyer Rudolph W. Giuliani.

The president has expressed concerns to advisers that a Biden Justice Department might investigate all of them.
