“I think what these indictments and filings show is that the president was at the center of a massive fraud — several massive frauds — against the American people," Nadler, who is likely to be the next chairman of the House Judiciary Committee, said on CNN's "State of the Union."

"And it’s now our job … to get to the bottom to this, to find out exactly what was going on, to find out the extent of the president’s involvement, to find out what did the president know and when did he know it," he added.

Prosecutors said in the Cohen filing that Trump directed illegal payments during the campaign, while the special counsel said that Cohen has provided information to investigators about "Russia-related matters."

The special counsel in a separate filing also accused Manafort of lying to federal investigators about his contacts with Trump administration officials and about his interactions with Konstantin Kilimnik, who is tied to Russian intelligence units.

Nadler said the filings show "a much broader conspiracy against the American people."

“All of these have to be looked at very seriously by the Congress, by the special counsel and by the Justice Department to see what actions we should then take," Nadler added.
