WASHINGTON — Several members of Congress in both parties Saturday questioned the legality of President Donald Trump’s move to launch military strikes on Iran.

While Republican leaders and many rank-and-file members stood by Trump’s decision to bomb Iran’s major nuclear enrichment facilities, at least two GOP lawmakers joined Democrats across the party spectrum in suggesting it was unconstitutional for him to bomb Iran without approval from Congress.

“While President Trump’s decision may prove just, it’s hard to conceive a rationale that’s Constitutional,” Rep. Warren Davidson, R-Ohio, who usually aligns with Trump, said on X. “I look forward to his remarks tonight.”

Rep. Thomas Massie, R-Ky., said in response to Trump’s social media post announcing the strikes: “This is not Constitutional.”

Massie introduced a bipartisan resolution this week seeking to block U.S. military action against Iran “unless explicitly authorized by a declaration of war or specific authorization for use of military force against Iran” passed by Congress.

In brief remarks from the White House on Saturday night, Trump defended the strikes but did not mention the basis of his legal authority to launch them without Congress’ having given him that power.

Sen. Bernie Sanders, I-Vt., reacted in real time during a speech in Tulsa, Oklahoma, slamming Trump’s actions as “grossly unconstitutional.”

“The only entity that can take this country to war is the U.S. Congress. The president does not have the right,” Sanders told the crowd, which broke out in “no more war!” chants.

Some Democrats called it an impeachable offense for the president to bomb Iran without approval from Congress.

Rep. Alexandria Ocasio-Cortez, D-N.Y., said Trump’s move is “absolutely and clearly grounds for impeachment.”

“The President’s disastrous decision to bomb Iran without authorization is a grave violation of the Constitution and Congressional War Powers,” she said on X. “He has impulsively risked launching a war that may ensnare us for generations.”

Rep. Sean Casten, D-Ill., said on social media: “This is not about the merits of Iran’s nuclear program. No president has the authority to bomb another country that does not pose an imminent threat to the US without the approval of Congress. This is an unambiguous impeachable offense.”
