McNeill has been a member of the state House since 2013, and was previously a Whitehall Township Supervisor.
“You always knew where Dan stood because he wasn’t shy about telling you,” state House Speaker Mike Turzai and Democratic Leader Frank Dermody said in a joint statement according to the Morning Call.
“All of us in the House appreciated Dan’s plainspoken style, and we respected his devotion to the people he represented.”
McNeill reportedly faced a “serious health challenge” but an official cause of death has not been released.
“People liked Danny because he sounded like one of them. I can hear his voice in my head, and he always made me smile,” state Rep. Mike Schlossberg (D-Lehigh) told the Morning Call.
