While he was U.S. president, Donald Trump was known to destroy, tear up, remove and even flush White House documents down the toilet. He often eschewed the White House switchboard, using his own cellphone or those of his aides to communicate.

The practices, which have drawn fresh attention as a result of the House of Representatives investigation into the Jan. 6 attack on the Capitol, have raised the question of whether Trump’s norm-breaking behavior was also a crime.

The House Oversight Committee said this week that Trump’s handling of documents appeared to constitute "serious violations” of the Presidential Records Act and announced an investigation of it.
