Alabama senate race close as some Republicans call for Moore's exit

(CBS) -- Despite growing calls for him to exit the race, Alabama Senate candidate Roy Moore isn't backing down.

Just three weeks remain before a special election to fill the seat vacated by Attorney General Jeff Sessions, and Moore says he has no intention of ending his campaign.

Nine women have accused the former judge of sexually inappropriate behavior.

Tina Johnson was 28 years old when she says Moore assaulted her in 1991. Johnson says it happened when she was in Moore's law office with her mother.

"We got up to leave, and when we did, my mother went first and he grabbed me from behind," she says.

Moore has denied all of the women's allegations and raised questioned about their timing. But outside of Alabama, many Republicans are questioning his fitness for office.

"I read his explanation, I heard his radio interview, and I did not find his denials to be convincing at all..." Senator Susan Collins (R-ME) told CNN.

President Trump has not publicly weighed in on the controversy over the Alabama election. The White House says the president has no plans to campaign for Moore.

But this morning on Fox News, Trump adviser Kellyanne Conway bashed Moore's liberal opponent.

"I just want everybody to know: Doug Jones, nobody ever seems to say his name, and they pretend that he's some kind of conservative democrat in Alabama... and he's not," she said.

Moore remains popular with many Alabama Republicans, particularly among evangelical voters. Recent polls indicate the race may be too close to call.
