A second Republican running for Mississippi governor refuses to be alone with women who are not his wife.

Former state Supreme Court Chief Justice Bill Waller Jr. told Mississippi Today that his decision is “common sense.”

“I just think in this day and time, appearances are important and transparency’s important, and people need to have the comfort of what’s going on in government between employees and people. And there’s a lot of social issues out there about that. My goal is to not make it an issue so that everyone’s comfortable with the surroundings and we can go about our business,” he said Monday.

The decision follows state Rep. Robert Foster’s refusal to allow a female reporter to spend a day riding along with him on the campaign trail, unless she had a male colleague with her.

Foster said he was following “the Billy Graham rule,” a practice named after the late evangelist that says a man cannot be alone with a woman to whom he is not married, even in professional situations.

“Now, in the #MeToo movement era, people could come back at me five, 10, 15 years later and accuse me of assaulting them, and I have no witness there to protect me from that accusation,” he said last week. “And so, I have to protect myself in both my professional and personal career.”

Waller’s campaign had previously said it was “standard practice to always have a member of the staff present when speaking to the press.”

A third Republican candidate, Mississippi Lt. Gov. Tate Reeves, has declined to say whether he also follows the rule.

“We’re not going to engage with a statement on the whole Billy Graham thing,” campaign spokesman Parker Briden said.
