Already, 43 House Republicans have announced this cycle they are retiring, running for another office or resigning outright, including Dent and House Speaker Paul Ryan.
Rep. Dent, amidst anger from the GOP base for his repeated attempts to block President Donald Trump's agenda, announced last September he will not seek re-election in 2018.
The Pennsylvania Supreme Court's February order creating new congressional districts in the commonwealth beginning next term included language that, if there were to be a special congressional election before the new term next January, it would be held under the 2011 congressional district map.
Congressional district employees, however, will continue to staff the offices under the supervision of the Clerk of the House of Representatives.
"I am proud to have worked with Representative Dent to make improvements in the Lehigh Valley and advance our constituents' shared interests in Washington", he said in a statement, in part. The special election would have to take place no less than 60 days after Wolf issues the write setting the date.
Both Republicans and Democrats are headed for contested primaries on May 15 for party nominations to replace Dent.
After discussions with my family & careful reflection, I have made a decision to leave Congress in the coming weeks.
"I am especially proud of the work I have done to give voice to the sensible center in our country that is often overlooked or ignored", he said in the statement.
