Who is one of the Senators currently serving for Pennsylvania?

John Fetterman is indeed one of the current Senators serving for Pennsylvania. He was elected to the position and has been active in the Senate since his inauguration. While it is true that Dave McCormick has been a prominent figure in Pennsylvania politics, he is not currently serving as a Senator. Instead, he has made attempts to run for the Senate but has not secured a seat. Thus, only John Fetterman represents Pennsylvania as a Senator. The choice indicating both individuals would be inaccurate since one of them is not serving in that position. This distinction is important for understanding the current political landscape in Pennsylvania.
