Lawmakers are heading home for a five-week break, but they’ll have a full plate of tough issues waiting for them they return to Washington.
On their way out the exits, lawmakers kicked the can on a number of political fights to September, setting themselves on a collision course with an unenviable—and already tight—fall schedule.

Iran
A months-long battle over the Iran nuclear deal will come to a head in mid-September, with lawmakers having less than two weeks to approve or disapprove of the agreement once they return to Congress on Sept. 8.
The White House has launched an all-out offensive to shore up support among Democrats and prevent a potential veto override. Administration officials will provide a final classified briefing to the Senate Foreign Relations Committee on Monday before lawmakers leave town.
Opponents want to use the August recess to build momentum for killing the deal, and they’re expected to heavily outspend supporters of the agreement. They’re hoping to put pressure on roughly a dozen Senate Democrats, including Sen. Chuck Schumer (D-N.Y.), expected to be the next Democratic leader.
Because the deal wasn’t finalized in time, Congress has 60 days of review time instead of the expected 30. Senate Democrats have brushed aside suggestions that puts them in a touch spot.
Most Democrats remain undecided heading into the break and will be barraged by constituents and TV ads trying to sway their decision.
