Sen. John Fetterman (D-PA) criticized his Democratic colleagues in Congress who have spoken out against Israel’s attack on Iran, calling it “astonishing” to see members of his party treat Israel’s actions as escalatory.

When Israel launched a missile attack on Iran late Thursday few if any lawmakers reacted out of the box faster than Sen. John Fetterman, who swiftly called for the U.S. to give Israel whatever it needed and later cheered on news of the deaths of Iranian generals and scientists.
