A California congressman called for a complete "pause" on President Donald Trump's agenda in response to the latest media reports on the administration's ties to Russia. "We may have an illegitimate president of the United States currently occupying the White House," Rep. Ted Lieu, D-Calif., said in a statement Thursday.

Lieu's office issued that statement after CNN reported Thursday the FBI has information indicating Trump associates might have coordinated with Russian operatives to release hacked information damaging to Hillary Clinton's presidential campaign. At a congressional hearing Monday, FBI Director James Comey said his agency is currently investigating Russian interference in the 2016 election campaign, as well as possible collusion between people within the Trump team and the Russian government.

"The bombshell revelation that U.S. officials have information that suggests Trump associates may have colluded with the Russians means we must pause the entire Trump agenda," Lieu said Thursday.

"Other than allowing routine governmental functions, there must be a total and complete shutdown of any agenda item being pushed by the Trump administration. Congress cannot continue regular order and must stop voting on any Trump-backed agenda item until the FBI completes its Trump-Russia collusion investigation," said Lieu, who was first elected to the House in 2014.

Lieu also called on Congress to form an independent commission and appoint a special prosecutor to investigate allegations of collusion. Devin Nunes, R-Calif., chairman of the House Intelligence Committee, was widely criticized for putting the independence and credibility of the committee in doubt after he bypassed his own committee and went to the White House and the press with unsourced revelations that U.S. intelligence agencies "incidentally" gathered communications of Trump associates.

"At this point in our nation's history, there is nothing more important than finding out whether or not high crimes were committed by associates of Donald Trump or possibly by Trump himself," Lieu said.
