President Trump's lawyers filed a brief on Monday urging the Senate to dismiss the impeachment charges against him and calling the House's impeachment process a "perversion" of the Constitution, The Associated Press reports.

The 110-page brief calls the House's impeachment case "flimsy," insists Trump did "absolutely nothing wrong," and says he has "been the victim of an illegitimate partisan effort to take him down," The New York Times reports. The House filed two impeachment articles against Trump — abuse of power for withholding aid to Ukraine in order to pressure that country to investigate his political rivals, and obstruction of Congress for blocking the House's impeachment inquiry.

The brief "does not deny that Mr. Trump pressured Ukraine to open investigations into Democrats," the Times writes. Instead it argues that this was within Trump's rights as president. As to the obstruction of Congress article, the lawyers say the president has a right to confidential deliberations.

The Senate trial on Trump's impeachment begins Tuesday. He is just the third sitting president to face such a trial. The Republican-controlled chamber is unlikely to convict him. Jessica Hullinger
