It alluded to plans to attack U.S. assets in the Middle East, saying "the number, dispersion, and size of U.S. military bases in the region are not a strength, but have doubled their vulnerability."

All U.S. House and Senate members are expected to receive classified briefings Wednesday on Iran and the U.S. military response. 

House Speaker Mike Johnson, a Louisiana Republican, told reporters Monday that Mr. Trump "made an evaluation that the danger was imminent enough to take his authority as commander in chief and make that decision." 

Minority Leader Hakeem Jeffries, a Democrat from New York, questioned the president's actions, saying in a letter to House Democrats that Mr. Trump has "not presented any evidence to Congress that Iran posed an imminent threat that required immediate and offensive military action." 

"The use of military force, which is offensive in nature, must be approved by the House and the Senate," Jeffries told reporters in a news conference on Capitol Hill Monday afternoon. "That's according to the Constitution. It's not optional, Donald. It's not." 

Iran's retaliatory strike bolstered calls from some lawmakers for Congress to intervene and assert congressional authority. Rep. Thomas Massie, a Kentucky Republican who last week aimed at stopping U.S. strikes, reiterated Monday his belief that the War Powers Act requires the president to withdraw from hostilities in Iran within 60 days.

"Whether you like it or not Congress will be voting on U.S. hostilities in Iran," Massie wrote on , noting that 57 lawmakers have signed onto his resolution.

But Johnson said, "I don't think this is the appropriate time for a war powers resolution."
