The House of Representatives has abruptly canceled plans to reconvene on May 4, after the Capitol physician warned Washington, D.C., remains a coronavirus hot spot, with the rate of infections continuing to rise. The decision threatens to further delay work on a massive new coronavirus relief bill.

Republican Senate Majority Leader Mitch McConnell, meanwhile, says the Senate will convene on Monday as scheduled. McConnell says he wants the next coronavirus stimulus bill to include liability protections for companies whose workers become ill or die after they’re ordered back to the job once states reopen their economies.
