Two of the candidates to be the Democratic nominee to run against Sen. Patrick J. Toomey, R-Pa., are also on opposing sides of the Democratic presidential primary.
On Thursday, Braddock Mayor John Fetterman posted his support for Sen. Bernard Sanders, I-Vt., on his Twitter account and in a video, saying, "the interests of corporations, the interests of the establishment, the interests of big money are not the interests of working families all across the Commonwealth or across this country."
Fetterman is running against Katie McGinty, former chief of staff to Gov. Tom Wolf, and former Rep. Joe Sestak, both of whom have ties to the Clintons.
McGinty served as chairwoman of the Council on Environmental Quality during the President Bill Clinton's administration and Sestak served as the director of defense policy on the National Security Council in the same administration.
Sabrina Singh, McGinty's communications director, said McGinty has always been a supporter of Hillary Clinton.
"We would welcome the opportunity to campaign with Secretary Clinton if the given the opportunity," Singh said.
Conversely, when Sestak's office was called he did not indicate who he was supporting.
"Joe just focuses on the people of Pennsylvania so he can continue to serve," said Michael Garrett, a Sestak spokesman.
