BRENTWOOD, N.H. — The case of a New Hampshire lawmaker charged with sexually and physically assaulting a 16-year-old girl is headed to trial.

Republican Rep. Eric Schleien, of Hudson, waived his arraignment hearing set for Wednesday, and a trial management meeting has been scheduled for Sept. 5.

The 29-year-old lawmaker was charged in April with one misdemeanor count of sexual assault and two misdemeanor counts of simple assault. Police say he struck up a conversation with the girl in Exeter in 2016 and told her he could help her learn about politics, but instead scared her with sexually explicit talk, sucked on her fingers and groped her inner thigh.

Schleien’s lawyer says he vehemently denies the allegations.
