House Speaker Nancy Pelosi told her colleagues that they will vote next week on the war powers resolution to limit President Trump’s authority on Iran, according to attendees. It was initially expected to be voted on this week.
Asked why there’s a delay, House Majority Leader Steny Hoyer said: “This is a discussion that started Sunday night ... This is something that has to be considered seriously and thoughtfully and correctly if we’re going to do this.”
The rocket attack on two Iraqi military bases housing US troops occurred at 1:30 a.m. local time (5:30 p.m. ET).
The Pentagon said more than a dozen missiles were launched from "Iran and targeted at least two Iraqi military bases hosting US military and coalition personnel at Al-Assad and Irbil."
US officials are working to determine the damage.
