After Iran launched hundreds of drones in an attack on Israel, House Speaker Mike Johnson said, “America must show our full resolve to stand with our critical ally.”

Johnson, R-La., said Israel is not alone and assured he will work with the White House “to insist on a proper response.”

He also called out the Biden administration, placing some blame on it for the attack.

“The Biden administration’s undermining of Israel and appeasement of Iran have contributed to these terrible developments,” Johnson said.

Other politicians reiterated Israel’s right to defend itself against such an attack and pledged U.S. support.

Sen. Roger Wicker, R-Miss., the top Republican on the Senate Armed Services Committee, said the U.S. commitment to Israel is “unwavering.”

“This is the moment for the United States to show we stand together with our allies,” the senator said. “Our shared enemies, including Iran and their proxies, need to know our commitment is unwavering.”

Sen. Ben Cardin, D-Md., chairman of the Senate Foreign Relations committee, said in a statement to NBC News that “Israel has an inherent right to defend itself against these attacks from Iran and its proxies — before, during, and after they occur.”

Cardin, somewhat opposing Johnson’s stance, said he supports President Joe Biden’s “iron-clad commitment to Israel’s security” and thanked his administration for taking what he said were necessary steps in recent days to support Israel as it prepared for an attack from Iran.

He reiterated that “the United States will continue to stand with Israel” and cautioned “Iranian regime leaders to not widen this already ill-conceived attack. Such escalation, especially targeting U.S. personnel and assets, should be dealt with swiftly and decisively.”

Others warned the attack could be far more extensive than it was initially thought to be.

Sen. Marco Rubio, R-Fla., the top Republican on the Senate Intelligence Committee, said on X, “The attack on #Israel by the regime in Iran is going to be more extensive than initially expected.”

So far, the U.S. has intercepted some drones launched at Israel and is working to do the same for incoming missiles.
