Congress returns to Washington this week to confront dramatic decisions on health care and the Supreme Court that may help determine the course of Donald Trump's presidency.

First, the president will have his say, in his maiden speech to a joint session of Congress on Tuesday night. Majority Republicans in the House and Senate will be closely watching the prime-time address for guidance, marching orders or any specifics Trump might embrace on health care or taxes, areas where some of his preferences remain a mystery.

Congressional Republicans insist they are working closely with the new administration as they prepare to start taking votes on health legislation, with the moment finally upon them to make good on seven years of promises to repeal and replace former President Barack Obama's Affordable Care Act. House Republicans hope to pass their legislation by early April and send it to the Senate, with action there also possible before Easter.

Republicans will be "keeping our promise to the American people," House Speaker Paul Ryan, R-Wis., said as he sent lawmakers home for the Presidents Day recess armed with informational packets to defend planned GOP changes to the health law.
