DALLAS (AP) — U.S. Rep. Joe Barton told a woman that he would complain to U.S. Capitol Police if sexually explicit photographs of him and other material from their relationship were to be exposed publicly, according to a published report. The Washington Post reported the threat Wednesday after Barton, a North Texas Republican, apologized for a nude photo of him that circulated on social media. The photo of Barton appeared on an anonymous Twitter account.
