Watch: Fox News cuts off Lev Parnas as soon as he admits Russia is behind Biden smears

Fox News cut away from its coverage of a House hearing Wednesday as soon as one of the witnesses testified that Russia was behind allegations against President Joe Biden.

While the hearing was on impeachment, a much-talked-about topic at Fox News, the network did not spend much time covering it after Lev Parnas, a former associate of Rudy Giuliani and a witness called by the Democrats, began speaking.

"The American people have been lied to by Donald Trump, Rudy Giuliani, and various cohorts of individuals in government and media positions," he told the House Oversight Committee. "They created falsehoods to serve their own interests, knowing it would undermine the strength of our nation."

Parnas explained how Giuliani had tasked him with traveling to Ukraine to gather "dirt" on Biden's family.

"The only information ever pushed on the Bidens in Ukraine has come from one source, and one source only — Russia and Russian agents," Parnas declared.

"The impeachment proceedings that bring us here now are predicated on false information spread by the Kremlin."

At that point, Fox News stopped carrying live coverage of the hearing.

"So this is a bit of a preview right now," anchor Bill Hemmer offered as the program moved away from broadcasting the live footage. "This hearing is going to be hot, so stand by for more on that."
