President Donald Trump on Wednesday vetoed the Iran War Powers resolution, a bipartisan effort to rein in presidential authority to use military force against Iran without congressional approval.

Trump called it a "very insulting resolution" and argued the measure was "based on misunderstandings of facts and law" in a statement.
"This indefinite prohibition is unnecessary and dangerous," the White House said in a separate message to the Senate on Wednesday.
Trump had long threatened a veto, which Congress isn't expected to have enough votes to override.
But passage of the resolution, which Democratic Sen. Tim Kaine of Virginia introduced following the President's decision to order a strike that killed Iranian commander Qasem Soleimani in January, represented a significant rebuke of the President and highlighted congressional support for efforts to check the executive branch's war-making powers.
