WASHINGTON - President-elect Joe Biden said Friday he is assembling a multitrillion-dollar relief package that would boost stimulus payments for Americans to $2,000, extend unemployment insurance and send billions of dollars in aid to city and state governments, moving swiftly to address the nation's deteriorating economic condition and the rampaging pandemic.

A last-ditch attempt by Democrats and the White House to restart negotiations on a new stimulus drew skepticism in Congress that a deal could be reached and written into law by Election Day.
