Sen. John Fetterman (D-Pa.), one of Israel’s strongest supporters on the left, publicly endorsed President Donald Trump’s decision to launch strikes against Iran, as lawmakers across party lines weighed in Saturday on Operation Epic Fury.

“President Trump has been willing to do what’s right and necessary to produce real peace in the region,” Fetterman wrote on X. “God bless the United States, our great military, and Israel.”

Sen. Lindsey Graham (R-S.C.), a longtime advocate of aggressive military action, praised Trump as both a “man of peace” and “evil’s worst nightmare.”

“As I watch and monitor this historic operation, I’m in awe of President Trump’s determination to be a man of peace but at the end of the day, evil’s worst nightmare,” Graham posted.

A U.S. official told Fox News Chief National Security Correspondent Jennifer Griffin that American and Israeli forces are targeting Iranian military infrastructure and ballistic missile sites that pose an “imminent threat.” The official added that while the U.S. is not targeting Iran’s leadership, Israel is.

Strikes reportedly hit the compound of Iran’s Supreme Leader, Ayatollah Ali Khamenei, 86, in central Tehran early Saturday.

In a video statement, Trump urged Iranian civilians to avoid military areas and suggested that once the operation concludes, the Iranian people should “take over your government.”

“God bless @POTUS for planning and now executing Operation Epic Fury, making America more safe and eventually more prosperous,” Graham added. He also predicted the potential collapse of Iran’s clerical regime, calling it “necessary and more than justified.”

Graham further claimed the operation could reshape Middle East diplomacy, arguing that the fall of Iran’s leadership could revive normalization efforts between Saudi Arabia and Israel.

Not all Republicans were supportive. Rep. Thomas Massie (R-Ky.), a frequent Trump critic, objected that the action had not been authorized by Congress, writing on X: “Acts of war unauthorized by Congress.”

Sen. Roger Wicker, chair of the Senate Armed Services Committee, praised what he called “decisive action” against “the world’s leading proliferator of terrorism.”

“This is a pivotal and necessary operation to protect Americans and American interests,” Wicker said. “The president has stated the operation’s goals clearly: thwart permanently the ayatollahs’ desire to create a nuclear weapon, degrade their ballistic missile force and production capacity, and destroy their naval and terrorism capabilities.”

As assessments of the damage continue, reactions from Capitol Hill underscore both rare bipartisan praise for the strikes and renewed debate over presidential war powers.
