RICHMOND, Va. (AP) — A Virginia legislator was indicted Monday on charges that he had an improper sexual relationship with a teenage girl, accusations the Democratic lawmaker denied and pledged to fight.

According to a special prosecutor’s statements in court papers, state Del. Joseph D. Morrissey and the 17-year-old girl had sex multiple times at the legislator’s law office in August 2013, and both texted their friends about the encounter. The next morning, Morrissey texted the girl and asked for “a nude photograph of her to help him fantasize about their next encounter,” said the prosecutor, Spotsylvania County Commonwealth’s Attorney William Neely.
