Lawyers for President Donald Trump and the Trump Organization are suing House Oversight and Government Reform Committee Chairman Elijah Cummings to block a subpoena for years of financial records from accounting firm Mazars USA.

The lawyers filed the lawsuit Monday in the U.S. District Court for the District of Columbia, saying the subpoena "lacks any legitimate legislative purpose, is an abuse of power, and is just another example of overreach by the president's political opponents."

Earlier this month, Cummings, D-Md., issued the subpoena to Mazars regarding Trump's finances to corroborate the testimony of his former personal lawyer and fixer, Michael Cohen, in February.

"We will not allow congressional presidential harassment to go unanswered," Jay Sekulow, one of Trump's personal lawyers, said in a statement.
