President Trump on Thursday called for Democratic Rep. Adam Schiff, who continues beating the drum on collusion, to be tossed from Congress.

“Congressman Adam Schiff, who spent two years knowingly and unlawfully lying and leaking, should be forced to resign from Congress!,” Trump wrote on Twitter.

Several hours later, Schiff responded to Trump and “his defenders in Congress.”

“You may think it’s okay how Trump and his associates interacted with Russians during the campaign,” Schiff posted on his Twitter account. “I don’t. I think it’s immoral. I think it’s unethical. I think it’s unpatriotic. And yes, I think it’s corrupt.”

Trump’s demand comes just days after Schiff, chairman of the House Intelligence Committee, doubled down on whether the president conspired with the Russians during the 2016 election.

“Undoubtedly, there is collusion,” he told the Washington Post on Tuesday. “We will continue to investigate the counterintelligence issues.”

Schiff said special counsel Robert Mueller, during his 22-month investigation, did not look into whether Trump came under the influence of foreign powers.

His insistence on collusion follows on the heels of Attorney General William Barr’s four-page summary of Mueller’s probe that concluded there is no evidence that either the president or his campaign associates conspired with the Russians.

Trump’s Twitter comments echo remarks he made to Fox News host Sean Hannity on Wednesday night.

“I heard they should force him off the committee, or off the committee chair. He should be forced out of office,” Trump told Hannity. “He is a disgrace to our country.”

The president said Schiff’s constant airing of the “collusion delusion” could be considered criminal because “he was making horrible statements that he knew were false.”

Trump, who has tussled with Schiff since entering the White House, called the congressman a “pencil neck” during a White House meeting Tuesday with Senate Republicans, Politico reported on Wednesday.

During the confab, Trump also said Schiff would be a horrible golfer because he would only be able to drive the ball 50 yards down the fairway.

A number of Republicans and White House administration officials have called on Schiff to step down since Barr released his summary of Mueller’s findings Sunday.
