CNN panel laughs in Rick Santorum's face after he says Devin Nunes 'thoroughly' investigated Russiagate

Rick Santorum was openly mocked by a fellow CNN panelist on Tuesday after he tried to claim that Rep. Devin Nunes (R-CA) and his House Intelligence Committee have "thoroughly" investigated ties between the Russian government and President Donald Trump's campaign.

During a panel discussion hosted by CNN's Brooke Baldwin, the former Pennsylvania Republican senator tried to brush aside any notion that the Trump campaign may have conspired with Russian agents by saying the president's congressional allies have already cleared him of any wrongdoing.

"The House of Representatives has examined this thoroughly," Santorum said.

At this point, panelist Keith Boykin burst out laughing while Baldwin tried to suppress laughter.

"Oh come on!" Boykin shouted. "They did not!"

Santorum continued to insist that no evidence of collusion between Trump and Russia had yet been leaked out, which led him to believe that the investigation was "a dry hole."

"The House investigation was a joke," Boykin retorted.
