Editor's note: Updates with response from Wolf's campaign

Sen. Scott Wagner will resign from his Senate seat on Monday to concentrate his efforts on unseating Gov. Tom Wolf in the November election.

Wagner submitted a letter to Senate President Pro Tempore Joe Scarnati, R-Jefferson County, indicating his intention to depart from the Senate seat he has held representing York County for the past four years.

Wagner won the Republican gubernatorial nomination in the May primary, beating out political newcomers Paul Mango and Laura Ellsworth.

Wagner's spokesman Andrew Romeo said in a statement, "Since winning his historic write-in campaign in 2014, it's been Scott's honor to serve the people of York in the state Senate. However, since Tom Wolf has taken office there has been nothing but gridlock in Harrisburg, and Scott realizes that the way he can bring about the most change and do the most good for the commonwealth is to devote all his time and energy toward getting elected governor and giving Pennsylvanians a different choice."

Gov. Wolf responded a couple hours later to the news, saying that Wagner's decision to resign "one week after skipping crucial votes to protect children in order to attend a political corporate policy summit, and one month before the budget deadline, proves that he is the very worst of Harrisburg."

The statement, issued by Beth Melena, communications director for the Wolf campaign, noted that Wagner was a confirmed nominee to attend the Republican Governors Association 2018 New York Corporate Policy Summit from May 22 to May 23.

During that time, she noted in the statement, that Wagner missed votes on keeping 17,000 sex offenders on Pennsylvania's registry, making domestic violence in the presence of children a separate crime, and requiring carbon monoxide detectors in child care facilities.

"Scott Wagner is only interested in furthering his own political ambitions, but his resignation does not erase his long record of supporting education cuts for our children, rolling back health care for hundreds of thousands of Pennsylvanians, and throwing seniors out of their nursing homes," the statement said.
