Ex-Bush adviser: GOP is spewing 'B.S. and baloney' about Mueller while doing Putin's dirty work

As GOP lawmakers do their best to undermine the FBI and Special Counsel Robert Mueller's investigation into possible Russian collusion with President Donald Trump's campaign team, a former Bush-era ethics attorney suggested another investigation be opened.

Appearing on MSNBC, Trump critic and Republican Richard Painter assailed GOP lawmakers who are attacking the FBI and undermining the rule of law, calling their attacks "a bunch of B.S. and baloney."

"What's going on here is that members of Congress want to carry President Trump's water, here, in attacking Robert Mueller," Painter said, "but it's not going to work because Robert Mueller is a Republican. He was appointed by a Republican Deputy Attorney General."

Painter said that if a second special counsel is appointed, that person should be looking into the millions of dollars donated to Republicans by Putin-allied Russians living in the U.S..

"These members of Congress are clearly very defensive about Robert Mueller," Painter said. "And none of those claims against Mueller have any basis."

Republicans like Rep. Devin Nunes (CA) who are trying to hamstring the Mueller probe are "fronting for Vladimir Putin," said Painter.
