In 2015, after a sexually explicit, mainly online relationship with a woman ended, Rep. Joe Barton (R-Texas) threatened to report the woman to the Capitol Police, according to a recording obtained by The Washington Post. Barton had reportedly sent the woman sexually explicit photos, videos, and messages over the course of their relationship, which began on Facebook in 2011.

The woman, who spoke to the Post on the condition of anonymity, recorded the 2015 conversation in which Barton confronted her about communications she had with other women connected to Barton. "I am ready if I have to, I don't want to, but I should take all this crap to the Capitol Hill Police and have them launch an investigation," he said, according to the recording.

On Wednesday, Barton apologized to his constituents after naked photos of him circulated on social media. In a statement, Barton, who is the longest-serving member of Congress from Texas, said he had sexual relationships "with other mature adult women" while separated from his second wife, before their divorce in 2015. "I am sorry I did not use better judgment during those days," he said. But Barton, who has reportedly hired a crisis communications firm, also said that he had suffered a potential crime over the released lewd photos. In Texas, it is a misdemeanor to intentionally publicize images or videos of someone's genitals or sexual activity without consent. Barton said the Capitol Police may be launching an investigation.
