Jeb Bush on Monday joined growing Republicans calls for Alabama GOP Senate candidate Roy Moore to step down after Moore allegedly had a sexual encounter with a minor.

“This is not a question of innocence or guilt like in a criminal proceeding, this is a question of what’s right and what’s wrong. Acknowledging that you’re dating teenagers when you’re 32 years old as assistant state attorney is wrong. It’s just plain wrong,” the former Republican presidential candidate and Florida governor said during an interview on CNBC.

“We need to stand for basic principles, and decency has to be one of those,” he continued. “In the really poisonous political environment we have right now, one of the rules I think has to apply is that when you attack somebody on the other party, and the other team, for doing something wrong, when it happens on your team you have an obligation, I think, to speak out as well.”

Moore has been under growing pressure from Republicans to drop out of the Senate race after The Washington Post published a story detailing an account from a 53-year-old woman who said she had a sexual encounter with Moore in 1979, when she was 14 years old and he was 32.

The report also included accounts from three other women who said Moore made advances to them around that time, when they were between 16 and 18 years old.

Bush said Monday the focus on Moore is potentially problematic as Republicans look to push forward tax reform in both chambers of Congress.
