President Donald Trump’s meeting with Republican senators turned tense after disagreements over a War Powers Resolution and related legislation on Iran, with sources saying he raised his voice and clashed with Sen. Bill Cassidy of Louisiana.

The discussion focused heavily on U.S. military authority, Iran policy, and a recent Senate resolution aimed at limiting presidential war powers, which some Republicans supported alongside Democrats.

Trump criticized GOP senators who backed the measure and also expressed frustration over broader party disagreements, including opposition to his “SAVE America Act” agenda.

Senators described the meeting as “spirited” and “lively,” with some noting disappointment but also attempts at unity, CBS News has reported.

Despite the tensions, Trump reiterated that Republicans must unify and emphasized passing his priorities ahead of upcoming elections.
