On Tuesday, House Intelligence Committee Chairman and Democratic Congressman Adam Schiff said that he believes support for impeaching President Trump is “gathering momentum” in the GOP.

His comments come after reports that Republicans in leadership, like Mitch McConnell and Liz Cheney, are supportive of the effort.

Schiff made his comments during an interview on CNN’s “Situation Room” with host Wolf Blitzer.

Schiff: ‘These Things Have A Way Of Gathering Momentum’

Blitzer said to Schiff, “The third-ranking Republican in the House, Congresswoman Liz Cheney, she nows says she will actually vote to impeach President Trump tomorrow when this resolution comes up for a vote.”

Blitzer added, “The last time you impeached President Trump, you did so with no Republican support in the House, no Republican support at all. So what does this development mean?”

Schiff replied, “It means she won’t be alone. There will be other Republicans influenced by her decision, and these things have a way of gathering momentum.”

Trump Called Schiff ‘Watermelon Head’ In October

“So I wouldn’t be surprised now to see a considerable number of Republicans join in supporting the impeachment resolution,” he added.

The Democrat then noted how significant support for impeachment from Senate Majority Leader Mitch McConnell could be in this effort.

“These reports that Mitch McConnell may be open to the impeachment charges as well is quite a potential earthquake in the Senate,” Schiff said.

Schiff is no stranger to battles with President Trump. He was one of the key advocates of RussiaGate during Trump’s entire first term in office.

In October, Trump called Schiff “watermelon head” at a presidential campaign rally in Gastonia, North Carolina.

Trump also said Schiff should be “locked up.”

Schiff Led First Impeachment Trial Against Trump

Schiff led the first impeachment trial against President Trump over alleged collusion with Russia in the 2016 presidential election.

Special Counsel Robert Mueller’s investigation found insufficient evidence to back up those allegations.

Progressive journalist Glenn Greenwald wrote at The Intercept in April 2019, “The two-pronged conspiracy theory that has dominated U.S. political discourse for almost three years – that (1) Trump, his family and his campaign conspired or coordinated with Russia to interfere in the 2016 election, and (2) Trump is beholden to Russian President Vladimir Putin — was not merely rejected today by the final report of Special Counsel Robert Mueller. It was obliterated: in an undeniable and definitive manner.”
