As Congress works on a rescue package to help shore up a U.S. economy hard hit by the coronavirus pandemic, a wide swath of business, from the solar power industry to casinos and hotels, along with doctors, nurses and educators are urging lawmakers to give them a share of the pie.

Senate Majority Leader Mitch McConnell promised “significant and bold new steps above and beyond what the House has passed.” And the White House is pitching an $850 billion aid package, with other proposals likely to follow.
