Billy Graham rule

The Modesto Manifesto or Billy Graham rule is a code of conduct among male evangelical Protestant leaders, in which they avoid spending time alone with women to whom they are not married.

[1][2] By Graham's own admission, though, he was not an absolutist in the application of the rule that now bears his name: his autobiography relates a lunch meeting with Hillary Clinton that he initially refused on the grounds that he does not eat alone with women other than his wife, but she persuaded him that they could have a private conversation in a public dining room.

[5] In March 2017, The Washington Post noted that U.S. Vice President Mike Pence, a practicing Evangelical, never eats alone with a woman other than his wife, Karen, and that he will not attend events featuring alcohol without her by his side.

[9][10][11][12] Polish science fiction writer Jacek Dukaj called this rule inevitable and likely to grow in popularity as an outcome of the #MeToo movement and cancel culture.

[6][17] When applied to workplace dinners or meetings in the United States, it could result in illegal labor discrimination under Title VII of the Civil Rights Act of 1964.
