WASHINGTON — Gun control, immigration and money to combat the Zika virus top the congressional agenda as lawmakers sprint toward the political conventions this month and a seven-week summer recess.

Amid all that, Republicans plan to squeeze in a meeting with Donald Trump on Thursday.

The House and Senate have just eight legislative days before their break, and lawmakers have scheduled a handful of politically charged votes with implications for incumbents in November’s election.

In the House, legislation to fight terrorism and a gun control measure that already failed in the Senate are planned for this week.

House Speaker Paul Ryan said a GOP plan to keep suspected terrorists from obtaining firearms would do so “without compromising a citizen’s basic bill of rights,” including the rights to bear arms and receive due process under the law.

In the Senate, immigration bills and legislation to impose labeling on genetically modified food are on tap. Unclear is whether Republicans and Democrats can resolve the dispute over funds for the mosquito-borne Zika virus.

A look at some of the issues:

n ZIKA: House Republicans rammed through a bill that would provide $1.1 billion in emergency money to fight Zika by cutting money from other government agencies. The legislation, to the anger of Democrats, would bar new funding for Planned Parenthood clinics in Puerto Rico and allow pesticide spraying that environmentalists argue would be harmful.

Senate Democrats have blocked the bill and another vote is expected this week, although progress is unlikely.

n GUN CONTROL: Bowing to election-year pressure from Democrats, Ryan, R-Wis., says the House will vote on a GOP proposal aimed at keeping suspected terrorists from obtaining firearms, a measure backed by the National Rifle Association.

Democrats want to vote on their own gun control bills, and they haven’t ruled out a return to disruptive tactics if they’re rebuffed.

Ryan indicated on Tuesday that Democrats are unlikely to get a vote.

The GOP bill would let the government block firearms purchases for suspected terrorists, but only if prosecutors can prove in court that the buyer is involved in terrorism. It would also establish a new office within the Department of Homeland Security to focus on preventing extremist groups from recruiting followers.

Democrats say the Republican bill is too weak. They want votes on one measure expanding background check requirements for gun buyers, and a second banning firearms sales to terror suspects without requiring prosecutors to first prove the buyer was embarking on terrorism.

n FAA REAUTHORIZATION: Key House and Senate lawmakers are close to a deal on a bill to extend the Federal Aviation Administration’s programs and policies, which are due to expire on July 15. Rep. Bill Shuster, R-Pa., chairman of the House Transportation Committee, has agreed to temporarily drop his contentious plan to privatize the nation’s air traffic control system in order to allow a bill to move forward.

Negotiations have focused on what policy provisions to include in the extension. There is strong support in both chambers to include an array of proposals to enhance airport security.

n IMMIGRATION: Senate Democrats are expected to block a GOP bill that would withhold congressional funding from so-called sanctuary cities that shield residents from federal immigration authorities.

Republicans also are proposing a bill to impose a mandatory minimum sentence of five years for any person who illegally re-enters the country after being removed.
