Sen. Jeff Flake took to Twitter while Sen. John McCain released a statement Thursday voicing their outrage regarding sexual abuse allegations that recently surfaced against Republican U.S. Senate nominee Roy Moore.

McCain called the allegations “deeply disturbing and disqualifying.”

“He should immediately step aside and allow the people of Alabama to elect a candidate they can be proud of,” McCain said.

Sen. Flake said if there is any “shred of truth” to the allegations against Moore he should step aside.

In an interview with The Washington Post, four women said Moore, now the Republican U.S. Senate nominee in Alabama, made sexual advances towards them in the late 70s and early 80s.

According to The Washington Post's report, the women were teenagers while Moore was in his early 30s.

One woman, Leigh Corfman, was 14 -- The Post wrote:

“Alone with Corfman, Moore chatted with her and asked for her phone number, she says. Days later, she says, he picked her up around the corner from her house in Gadsden, drove her about 30 minutes to his home in the woods, told her how pretty she was and kissed her. On a second visit, she says, he took off her shirt and pants and removed his clothes. He touched her over her bra and underpants, she says, and guided her hand to touch him over his underwear.”

The Arizona senators join Majority Leader Mitch McConnell and, what The Post referred to as, a “growing chorus of Senate Republicans” in saying Moore should exit the Alabama Senate race.

Moore has denied the allegations.
