Rep. Brad Sherman has drafted an article of impeachment against President Donald Trump that he plans to soon file and eventually raise for consideration on the House floor.

The California Democrat’s article argues that Trump obstructed justice by using his authority as president to hinder or terminate a criminal investigation into his former national security advisor Michael Flynn. It cites Trump requesting then FBI director James Comey to curtail the bureau’s investigation into Flynn and then later terminating Comey and admitting that his main reason for doing so was related to the Russia investigation.

“In all of this, Donald John Trump has acted in a manner contrary to his trust as President and subversive of constitutional government, to the great prejudice of the cause of law and justice and to the manifest injury of the people of the United States,” the article reads.

Sherman sat in the audience during Comey’s public testimony before the Senate Intelligence Committee Thursday.

In a dear colleague letter, Sherman said he hopes the House Judiciary Committee would expeditiously consider the article, but if the panel does not take it up, he will offer a privileged motion on the House floor.
