“The ethics committee will have to consider the matters that have been litigated in the campaign should that particular candidate win,” McConnell said on ABC’s “This Week” earlier this month. “And I’m confident they’ll come up with the right conclusion.”

The committee has a range of penalties it can recommend to the Senate for a member, including expulsion, censure, payment of restitution, a change in seniority or positions of responsibility, public or private letters of admonition and training or education.

In its history, the Senate has expelled 15 members — one for treason and 14 for supporting the Confederate rebellion. The last expulsion occurred in 1862. The last member to face expulsion was Sen. Robert Packwood, R-Ore., who resigned in 1995 before the vote was taken.
