Rep. Terri Sewell, D-Ala., on Sunday urged Alabama voters to reject Republican Alabama Senate candidate Roy Moore's bid for office, saying his character wasn't fit for the position.

"At the end of the day when Roy Moore, if he should win, goes to Washington, we will always be questioning his character," Sewell told ABC's "This Week." “Roy Moore will only take us backwards and harken us back to the days of segregation.”

"They're putting party before people, party before principle," the only Democrat in Alabama's congressional delegation explained of the GOP. "There's no reason to doubt these women: independent corroboration, contemporaneous accounts, and eight people who didn't know each other."

Moore has been accused of engaging in inappropriate sexual behavior with teenaged girls when he was in his 30s.

But Sewell admitted Democratic challenger Doug Jones was mistaken in sending out a mailer that asked voters to compare the allegations made against Moore to a situation in which an African-American man was accused of similar claims.

"I don't think that the folks are concentrating on one piece of literature," she said. "We have to look at the whole body of evidence and facts that Doug Jones has been saying as to why he's the right candidate for the state of Alabama."

Sewell also urged voters to cast their ballot based on the "full body of issues," as Jones' critics hit the Democrat for his advocacy of pro-abortion rights.

The special election for Attorney General Jeff Sessions' old seat is set for Dec. 12.
