The flashpoint is the SAVE America Act...
Trump ties FISA reauthorization to SAVE America Act (voter ID mandate) to pressure Senate GOP; Majority Leader Thune refuses. GOP senators privately admit opposition stems from anti-Trump sentiment, not policy merits, exposing party fracture over executive authority.
Divides over what GOP priorities should be ahead of this fall's midterm elections are testing the relationship between President Trump and Senate Republicans.
President Donald Trump may be the head of the Republican Party, but when it comes to the Senate, Majority Leader John Thune is still in charge.
Trump is fixated on passing the SAVE Act to help Republicans in the midterms.
