Republican senators are increasingly frustrated with the White House's interference in their legislative agenda. The tensions are particularly acute on issues requiring Democratic support to overcome Senate filibuster rules, including efforts to reauthorize a lapsed surveillance law that allows intelligence agencies to monitor foreign threats.
Beyond domestic legislation, Senate Republicans have also criticized Trump's foreign policy moves. Several GOP senators have sharply attacked the administration's interim deal with Iran, with one calling it "the worst foreign policy blunder in decades." The agreement, which reopened the Strait of Hormuz in exchange for sanctions relief, has generated significant skepticism among Republicans concerned about concessions made to Tehran.
