HARRISBURG — Democratic U.S. Rep. Mike Doyle, the dean of Pennsylvania’s congressional delegation, said Monday he will not seek another term in office in next year’s election, bringing his career in Washington to an end after 28 years.

Doyle said at a news conference at his Pittsburgh office that it is time to pass the torch to a new generation, as the pandemic accelerated his thoughts about retirement plans with his wife and redistricting will likely bring substantial change to the district’s boundaries.

Doyle, 68, was first elected in 1994, and served in office as Pittsburgh transformed its economy from steel to high-tech.

His district includes all of Pittsburgh and some of its increasingly leftward-leaning suburbs, and has easily won re-election in the heavily Democratic district.
