Trump and Republican senators had a contentious meeting on Capitol Hill on June 25 over legislative priorities including war-ending talks and Pentagon spending, with senators pushing back on the administration's approach. Rep. Stutzman characterized the conflict as constructive disagreement, while Vice President Vance held a separate dinner with GOP senators the same evening to smooth tensions. The dispute reflects deeper Republican divisions over how quickly to wind down the Iran conflict and what conditions should accompany defense spending increases.
