State Rep. David Leitch (R-Peoria) will not seek re-election after his term ends in 2017.

"It's been the honor of my life to represent central Illinois for nearly three decades," Leitch said via statement. "I cannot thank the people of the 73rd District enough for the privilege of serving in the General Assembly."

Leitch is the longest-serving Republican in the state legislature, having been in office since 1989. He has been a strong advocate for disabilities rights and mental health care in the state legislature. He points to his part in passing the first law requiring insurance coverage of mammograms as a great accomplishment during his time in office.

The Republican lawmaker also helped save Bartonville's Keystone Steel & Wire. He helped the company get a $10 million loan to remain open and after it was repaid, the money was placed in a Peoria County fund that is tapped for ongoing economic development.
