Republicans fear that tension between Donald Trump and the Senate’s top GOP lawmaker could sabotage the party’s midterm prospects. GOP lawmakers are frustrated by the charged silence between the president, 80, and Senate Majority Leader John Thune, 65, who, according to Thune, speak only on an “as-needed basis.” “We need to be talking up the wins, talking about how crazy Democrats are, and instead we are knifing each other,” one GOP senator told CNN. Trump moved to oust Sen. John Cornyn, a key Thune ally, in favor of MAGA-aligned candidate Ken Paxton. Senate Majority Leader John Thune has previously poured cold water on Trump's filibuster scheme.
