GOP representative Bryan Slaton resigned from the Texas House of Representatives on Monday in order to avoid an expulsion vote after an investigation into his inappropriate sexual conduct with a 19-year-old aide.

Slaton, 45, resigned in a letter to Texas Gov. Greg Abbott.

“My decision today is to ensure that [my constituents’] expectations will continue to be met by a new representative who will also work hard on their behalf,” he wrote.

“I look forward to spending more time with my young family, and will continue to find ways to serve my community and all citizens across our great state.”

The House had planned to vote whether to expel Slaton on Tuesday following an investigation into his conduct.

The five-person House Committee on General Investigating unanimously recommended he be expelled for engaging in inappropriate workplace conduct, specifically sexual harassment and retaliation.

“Slaton’s misconduct is grave and serious,” the committee’s report said. “He took advantage of his position to engage in sexual conduct after completing training in which he had been advised that conduct of this type was harassment because of the power imbalance.”

Three female staffers between the ages of 19 and 21 made allegations against Slaton in early April. A 19-year-old staffer told the committee that she had sex with Slaton at his Austin apartment after she consumed “a lot of alcohol” and felt “really dizzy.”

“‘In the moment, obviously, I had too many drinks. Kind of hard to think in the moment when you’re intoxicated. But now that I look back at it, it was definitely an inappropriate situation,’” the report quoted the aide.

The aide reported buying Plan B for herself the next morning to prevent pregnancy.

According to the report, Slaton then engaged in harassment and retaliation to intimidate the aide and others into not talking about his conduct. The aide feared she would lose her job.

Had he not resigned first, Slaton would have been the first Texas House member to be expelled since 1927.
