Story summary

Sen. John Fetterman, D-Pa., loudly denied on Capitol Hill that he would switch to the Republican Party, telling reporters, “I’m not going to be a Republican!” Frustrated with persistent questions about his loyalty to the Democratic party, Fetterman emphasized, "If I turn a Republican, then I’ll be a liar." His comments came after being asked similar questions while getting into an elevator. Despite growing distance from Democrats due to his strong support for Israel and Prime Minister Benjamin Netanyahu, Fetterman vowed he would not defect. He faces ongoing speculation about leaving the Democratic Party, especially since he has appeared on Fox News criticizing left-wing members of his own party. Fetterman remains adamant that he will stay a Democrat until at least 2028 when he is up for reelection.
