Trump has suggested the FBI or the Justice Department investigate the matter.
Ryan on Sunday suggested the Federal Election Commission should investigate.
“You can understand why the Democrats are mad about this,” he also said. “They should be. I’ve never seen anything like this.”
Ryan, in the wide-ranging interview, also expressed optimism for the tax-reform plan that congressional Republicans released last week.
“I feel very good about it,” he said about the plan and its path to President Trump’s desk for signature.
Ryan said the GOP-controlled House is on track to pass the bill by Thanksgiving, with the GOP-controlled Senate to follow in about a week.
He also acknowledged that the House this past summer passed a measure to repeal and replace ObamaCare, only to have the effort fail in the Senate. And he argued the tax-reform plan will be better, more coordinated.
“We did things differently this time because of the health care experience,” Ryan told Fox News. “We worked for the Senate ahead of time, from the summer on, to put this bill together, to basically create a framework of this bill: House, Senate, and the White House, and launch this thing together, and be very coordinated.”
