Businesses suffering the most from the coronavirus crisis could receive a second round of financing under a federal emergency relief program, US Treasury Secretary Steven Mnuchin said Friday. He said sectors that have been especially battered such as travel and restaurants are prime candidates for another round of support under the Paycheck Protection Program, which was launched in April to provide support to smaller enterprises devastated by coronavirus shutdowns. “There should be a second check available to the businesses that are the hardest hit,” Mnuchin said in testimony before a House committee, noting the government has $130 billion in unspent PPP funds. However, he said he favored a revenue test to determine which companies should be supported, and pledged to work with Congress to determine the size of businesses eligible for a second round of financing. Mnuchin is leading the effort to negotiate a new support package with the Democratic-led House of Representatives as the coronavirus outbreak worsens in much of the country. Hanging in the balance is $600 per-week in additional unemployment benefits that is set to expire at the end of July.
