Of all the lawmakers who gushed conspiracy theories connecting President Trump with Russians intent on altering the outcome of the 2016 presidential election, none was as prolific as Rep. Adam Schiff.

The California Democrat was everywhere, omnipresent on cable news shows that pressed the collusion allegations for more than two years. The leader of the movement was Schiff, who made all kinds of unsupported allegations. He said there was “damning evidence” of collusion, “more than circumstantial.” He compared the so-called scandal pushed by Democrats and their liberal lapdogs in the media as “beyond Watergate.”

“The Russians gave help and the president made full use of that help. That is pretty damning, whether it is proof beyond a reasonable doubt of conspiracy or not,” Schiff said nearly near years ago on CNN.

But all that fell apart last weekend when Attorney General Robart Barr released a four-page summary of the report compiled by special counsel Robert Mueller. Based on the final report from Mueller, Barr said on Sunday that investigators “did not find that the Trump campaign or anyone associated with it conspired or coordinated with Russia in its efforts to influence the 2016 U.S. presidential election.”

Now, prominent Republicans and top GOP lawmakers are calling for Schiff to resign from Congress, or at the very least step down from his post as chairman of the House Intelligence Committee.

“He’s been on every TV show 50 times a day for practically the last two years, promising Americans that this president would either be impeached or indicted,” White House adviser Kellyanne Conway said on Fox News. “He has no right, as somebody who has been peddling a lie, day after day after day, unchallenged. Unchallenged and not under oath. Somebody should have put him under oath and said, ‘You have evidence, where is it?’ “

“This man leads the Intelligence Committee in the House,” she said. “He ought to resign today.”

Trump, who once called Schiff “Little Adam Schitt” in a post on Twitter, also weighed in on the issue, albeit without naming Schiff. “There are a lot of people out there that have done some very evil things, very bad things, I would say treasonous things against our country,” Trump said Monday in the Oval Office. “Those people will certainly be looked at.”

Republican leaders ramped up those calls Tuesday.

Republican National Committee Chairwoman Ronna McDaniel said Shiff and other Democratic leaders who pushed the allegations “should be removed from their chairmanships.”

“They owe the American people an apology. They owe this president an apology, and they have work to do to heal this democracy because this is our country we are talking about,” McDaniel said.

House Minority Leader Kevin McCarthy (R-CA) echoed that call. “He owes an apology to the American public,” McCarthy said. “There is no place in Adam Schiff’s world or in Congress that he should be chair of the intel committee.”

McCarthy added: “There is no way he could lead the intel committee and he should step back.”

But don’t look for Schiff to do the right thing after his spurious allegations. On Monday, he again asserted that evidence of collusion is in “plain sight.” And he’s clearly relishing his role as a “Resistance” leader.

“For whatever reason over the last year and a half, the president has viewed me as a threat,” he told The Associated Press. “His allies in Congress have likewise come to his assistance in attacking me. It comes with the job, and I take it as a sign of effectiveness that they feel the need to go after me.”

House Speaker Nancy Pelosi, a fellow California Democrat, also dismissed calls for Schiff to vamoose, calling them “absolutely ridiculous.”

“Democrats aren’t going to be intimidated by the White House or Congressional Republicans,” Pelosi spokeswoman Ashley Etienne said. “We’re not going to be distracted from securing the release of the full Mueller report and the underlying evidence, and we will continue to pursue legitimate oversight because that’s what the Constitution requires.”
