WASHINGTON (AP) – Election-year politics will rule the calendar when Congress returns from a seven-week recess.

Lawmakers will have a little more than four weeks beginning Tuesday before they are scheduled to leave town again before the election.

There’s a lot on the docket, but there’s only one thing that Congress must do in the coming month: Figure out a way to keep the government open before spending legislation expires Oct. 1.

Beyond that, there are other high-priority items on the agenda, such as approving funds to combat the mosquito-borne Zika virus, and defense policy legislation determining how much is spent on the nation’s military. Other measures, such as gun-control legislation and the nomination of Judge Merrick Garland to the Supreme Court, face longer odds for passage.
