Washington: One of President Joe Biden's top economic aides on Sunday will press Democratic and Republican senators for a fresh $1.9 trillion in coronavirus relief to help struggling Americans and avert a larger economic crisis.Brian Deese, director of the National Economic Council, said he would speak to the senators to make the case for a large rescue plan."We can't wait," White House spokesperson Karine Jean-Pierre told reporters. "Just because Washington has been gridlocked before doesn't mean it needs to continue to be gridlocked."The COVID-19 pandemic has killed more than 417,000 Americans, thrown millions out of work and is infecting more than 175,000 Americans per day, posing an immediate crisis to the Biden administration.
