HARRISBURG, Pa. (WHP) — Pennsylvania Sen. John Fetterman cast the deciding vote for a resolution that would’ve directed President Donald Trump to withdraw armed forces from Iran.

Fetterman was the only Democrat to vote against the War Powers Resolution on Thursday. The resolution was rejected by a 49-50 vote.

Republican Sen. Dave McCormick also voted against the resolution Thursday.

Fetterman has publicly supported the war in Iran from the get-go, but an increasing number of Republicans have opposed it. On Thursday, three Senate Republicans voted in support of the resolution.

If the resolution passed, it would require Trump to receive congressional approval before continuing military action in Iran. The conflict started Feb. 28, when the U.S. and Israel launched joint airstrikes against Iran.

Fetterman has not released a statement on his most recent vote, but he previously said he believes military action is the only way to prevent Iran from acquiring a nuclear weapon.

State Rep. Malcolm Kenyatta (D-Philadelphia) went after Fetterman on X, calling him “an utter disappointment.”

Rep. Chris Deluzio (D-Beaver/Allegheny) wrote that Fetterman’s vote will “keep the Iran War raging.”

“This reckless war has cost American lives, innocent lives, tens of billions of dollars, and higher prices on nearly everything here at home,” Deluzio wrote on X. “John and 49 Republican Senators voted in favor of all of that.”
