WASHINGTON -- The head of the Senate Republican campaign committee says if Roy Moore wins his race in Alabama, the Senate should vote to expel him.

Sen. Cory Gardner of Colorado says in a statement that he believes the women who accused Moore of sexual misconduct and that they spoke with "courage and truth." Gardner says what they recounted proves Moore is unfit to serve in the Senate and should not run for office.

Gardner says if Moore refuses to withdraw from the Alabama race and wins, "the Senate should vote to expel him, because he does not meet the ethical and moral requirements of the United States Senate."

A new accuser has come forward, alleging that Moore assaulted her when she was 16. Moore calls that new allegation part of a "witch hunt" against him.
