US Treasury Secretary Steven Mnuchin unveiled a new $916 billion pandemic aid proposal, aiming to break a months-long deadlock in Congress over additional aid to coronavirus-ravaged US economy. The proposal, slightly larger than a $908 billion measure unveiled by a bipartisan group of senators last week, would include “money for state and local governments and robust liability protections for businesses, schools and universities,” Mnuchin said in a statement, all of which have been key sticking points in negotiations.
