Speaker Nancy Pelosi announced that she clinched a deal with Treasury Secretary Steven Mnuchin on a large-scale coronavirus response package meant to provide paid leave for workers, expand food aid and support widespread testing for the illness at no cost to patients.

The development sent a wave of relief across Capitol Hill, which had been nervously awaiting the results of two days of backroom negotiations. The House is expected to pass the legislation quickly, with the Senate likely to follow suit as early as Monday.
