President Donald Trump's decision to launch a military strike on Iran's nuclear sites without fully consulting the U.S. Congress layered a partisan approach onto a risky action, particularly because the White House briefed top Republican leaders beforehand without doing the same for Democrats. While House Speaker Mike Johnson, Senate Republican leader John Thune and the GOP chairman of the Senate Intelligence Committee were all briefed before the action, their counterparts were not. Senate Democratic leader Chuck Schumer was given a perfunctory heads-up by the White House shortly before the strikes were made public.
