U.S. Treasury Secretary Steven Mnuchin on Tuesday unveiled a new $916-billion pandemic aid proposal, aiming to break a months-long deadlock in Congress over additional aid to the coronavirus-ravaged U.S. 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. 

Those elements all have been key sticking points in the negotiations between Democratic and Republican lawmakers. 

Mnuchin said he presented the proposal to Democratic House Speaker Nancy Pelosi on Tuesday evening, and also reviewed it with outgoing President Donald Trump and Republican Senate Majority Leader Mitch McConnell.
