House votes to bar Trump from striking Iran without congressional approval

The big picture: "The 251-170 vote reflects lawmakers’ growing desire to take back long-ceded authority over matters of war and peace from the executive branch," writes the New York Times.

• The House bill includes other restrictions on Trump's foreign policy, including a yearlong ban on the sale of certain munitions to Saudi Arabia and the United Arab Emirates linked to their military operations in Yemen, per USA Today.

Catch up quick: In June, Trump said that he didn't need congressional approval to attack Iran.

• When Iran shot down a U.S. drone last month, Trump ordered a retaliatory strike, but abruptly scrapped the mission at the last minute.
• Earlier this week, three Iranian boats attempted to block a British tanker in the Strait of Hormuz, according to Britain's Ministry of Defense.

What's next: The vote tees up a confrontation on the Iranian restriction between the House and Senate as they try to work up a compromise version of the defense bill.
