Rep. Joe Barton of Texas said the Capitol Police has started an investigation into the release of a nude photograph of him. Barton apologized on Wednesday after the photo circulated on social media. Barton issued a statement saying that while separated from his second wife, prior to their divorce in 2015, he had sexual relationships “with other mature adult women.” The 68-year-old Republican said each relationship was consensual and has since ended. Barton has no plans to step down.
