Washington (CNN) House Judiciary Committee Chairman Jerry Nadler said Democrats are not going to wait for special counsel Robert Mueller to conclude his investigation to move forward with their investigations into President Donald Trump.

Nadler told CNN that once the House Judiciary Committee receives Mueller's final report on his investigation into Russian interference in the 2016 presidential election that "we will make sure it is public."

However, "we are not going to wait for the Mueller report. There is plenty for the Judiciary Committee to look into right now," the New York congressman said in an interview Friday with CNN's John Berman on "New Day."

"Specifically the attempt to have a massive fraud on the American people in terms of rigging an American presidential election and undermining the integrity of the election," he said. "And we have to look into that, whether it's by hush payments or by collusion with Russians or by any other means."

In a case Mueller's team referred to the US attorney for the Southern District of New York, Trump's former attorney, Michael Cohen, pleaded guilty in August to two campaign-finance violations tied to payments he made or orchestrated to adult-film star Stormy Daniels and former Playboy model Karen McDougal to stay silent about alleged sexual encounters with Trump.
