Ex-Bush ethics czar calls on Congress to investigate Trump -- and Mike Pence -- for 'illegal acts'
Richard Painter (CBS News)

Former White House ethics lawyer and Democratic Senate candidate Richard Painter argued on CBS Monday night that there is much more evidence against President Donald Trump for obstruction of justice than there ever was against President Richard Nixon before he resigned in disgrace.

The difference between the two situations? Congress, Painter said.

"We have far more evidence of abuse of power and obstruction of justice than we had in 1973 when I was 12 years old and the House and the Senate convened the Judiciary Committees to have hearings with respect to Watergate and President Nixon. We're well beyond that point. And yet the House and the Senate won't do anything at all.

"We need to have those hearings, we need to find out who in this administration has been complicit in these illegal acts," he continued. "We need to find out what the role of the vice president, Michael Pence, was in these illegal acts. This is critically important. And then when you have the facts, the next step is to decide what to do with it. Impeachment starts in the House of Representatives, and then it goes to the Senate."
