Republican Maryland Gov. Larry Hogan called on Alabama U.S. Senate candidate Roy Moore to exit his race over allegations that he sexually pursued teenage girls.

On Twitter, Hogan said Saturday that Moore would be "unfit" to serve in the Senate if he were elected.

"Roy Moore’s defenders should ask themselves if they would be so quick to excuse him if the victim was their daughter or if the offender was a Democrat," he said. "He is unfit for office and should step aside. Americans are better than this."

A Washington Post report on Thursday said four women alleged Moore sought sexual relations with them when they were teenagers. According to one of the allegations, Moore sexually assaulted a 14-year-old girl more than 30 years ago.

Moore has denied the allegations. Speaking Saturday at a Veterans Day event in Vestavia Hills, Ala., he said, that the charges are "completely untrue" and, "I have the highest regard for the protection of young children."
