Today, Speaker Mike Turzai announced May 21, the same day as the Pennsylvania primary, as the special election date to fill the open state House seat vacated by Rep. Brian Ellis (R-Butler).

Ellis resigned from the state House on Monday afternoon in the midst of a sexual assault investigation.

In January, the Philadelphia Inquirer reported that Ellis was under criminal investigation into allegations that he had sex with a woman while she was “incapacitated and without her consent, according to multiple sources with knowledge of the inquiry.” The alleged assault had taken place in late 2015 in his Harrisburg residence and the Dauphin County District Attorney’s office is conducting a criminal investigation.

Calls mounted from GOP leadership and Gov. Tom Wolf for Ellis to resign days after the allegation became public.

Ellis’s resignation letter stated he was resigning in the “best interests” of his family, residents of the 11th district, and his own health.

Ellis represented the 11th district from 2005 until this week.

The nominees for the special election will be selected by the parties.
