A top California Democrat blasted the White House and House Intelligence Committee Chairman Devin Nunes, accusing them of seeking to "cover up" ties between Russian officials and the Trump campaign. 

Committee member Rep. Eric Swalwell called on Nunes to recuse himself from the Russia probe, criticizing Nunes for cancelling today's public hearing on Russia.  

The hearing was supposed to include testimony from former acting attorney general Sally Yates. 

Earlier today, Sean Spicer dismissed as "100 percent false" a Washington Post report which stated that the White House sought to block Yates from testifying to Congress.

In a statement, the committee's ranking Democrat asked whether Nunes cancelled the hearing so that the White House would not have to assert executive privilege over her testimony.

Swalwell dismissed Spicer's denial, quipping that if the press secretary says something, "the opposite is probably happening."

He noted that former national security adviser Michael Flynn and Attorney General Jeff Sessions claimed to have forgotten about talks with the Russian ambassador.

"When you put all of this together, what you see is behavior that is consistent with a cover-up," said Swalwell, calling for an investigation by an independent commission.
