Senator Pat Toomey picked up a valuable supporter today.

According to Jonathan Tamari of the Inquirer, former New York City Mayor Michael Bloomberg is endorsing Toomey’s re-election.

Sen. Toomey has fought for a background check bill, a cause close to Bloomberg’s heart. As a result, the McGinty team could make the argument that this action should be expected. Unfortunately for them, though, Bloomberg is also backing other statewide Democratic candidates like Josh Shapiro and Joe Torsella.

“In the wake of Newtown, Pat Toomey crossed party lines to lead the fight to reduce gun violence in America by co-sponsoring legislation to close the background check loophole,” Bloomberg said. “His pragmatic leadership in Washington deserves the support of every Pennsylvanian.”

“In Harrisburg, Pennsylvania can count on Josh Shapiro and Joe Torsella to demonstrate bipartisan leadership and achieve real results in the areas of public safety and fiscal accountability,” the billionaire continued. “I hope Pennsylvania voters of both parties can support all three — Toomey, Shapiro and Torsella — this November.”

“Pat Toomey is not a moderate on gun safety, and he’s certainly not a pragmatic leader,” McGinty Communications Director Sean Coit responded. “Just two weeks ago, Pat Toomey bragged to Pennsylvanians about his A rating from the gun lobby, and in June, he voted against blocking terrorist from buying guns. No endorsement is going to change the fact that Pat Toomey is in lock step with the gun lobby in Congress.”

Just last week, Bloomberg spoke out against GOP presidential nominee Donald Trump in a speech to the Democratic National Convention.
