WASHINGTON, D.C. — Democrats are set to take control of both chambers of Congress after Tuesday’s election, putting the cost of groceries, housing and energy at the center of an early test for the incoming majority and President Donald Trump.

The election changes who sets the congressional agenda in January. Democrats will be able to decide which proposals get hearings and votes, while Trump remains in office with the power to veto legislation.

That split leaves room for negotiations on spending and household costs, but both sides face hard choices about which measures they can agree on and how to pay for them. The pace of inflation and the actual prices families pay are separate measures, and a slower rate of inflation alone does little to unwind earlier price increases.

The first test will be whether proposals on everyday costs can move from campaign promises to bills with a path through both chambers and the White House.
