Congress passed a similar resolution in January, which stopped short of fully restraining Trump’s ability to strike Iran, leaving an exception for situations when military force is “necessary and appropriate to defend against an imminent attack” on Americans.

1 US soldier and 1 US contractor were killed in an attack on al-Taji base in northern Baghdad Wednesday. No force has claimed responsibility for the strike, the most serious attack on foreign forces in Iraq this year.
