(CNN) Sen. Elizabeth Warren said Wednesday that Congress' immediate priorities should be avoiding a constitutional crisis and protecting special counsel Robert Mueller, not impeaching President Donald Trump.

"What Congress needs to do right now is we need to make sure that special (counsel) Mueller is fully protected from being fired by Donald Trump," the Massachusetts Democrat told CNN's John Berman on "New Day," one day after Trump's former campaign chairman, Paul Manafort, was convicted on eight counts of financial crimes, while ex-Trump lawyer and fixer Michael Cohen pleaded guilty to eight criminal counts, including tax fraud and campaign finance violations.

When he plead guilty, Cohen implicated Trump himself, admitting that "in coordination and at the direction of a candidate for federal office," he kept information that would have harmed Trump from becoming public during the 2016 election cycle.

Warren didn't call for Congress to take immediate action against Trump, instead suggesting Congress wait until Mueller's probe into Russian meddling in the 2016 election concludes.

"Protect Robert Mueller, let him finish his investigation, let him make a full and fair report to all of the American people," Warren advised as next steps. "And when we've got that, then we can make a decision on what the appropriate next step is."
