US President Donald Trump on Tuesday rejected a $900 billion ($1.17 trillion AUD) , calling it "a disgrace" and demanding that politicians more than triple relief payments to Americans.
While he did not explicitly say he would not sign the bill, which passed overwhelmingly Monday in both houses of Congress, Mr Trump made clear he would not accept the legislation.
"It really is a disgrace," he said in a four-minute video message posted to Twitter.
"I am asking Congress to amend this bill and increase the ridiculously low $600 ($790 AUD) to $2,000 ($2,650 AUD), or $4,000 ($5,305 AUD) for a couple," he said, referring to relief checks meant to go out to most Americans.
"I'm also asking Congress to immediately get rid of the wasteful and unnecessary items from this legislation, and just send me a suitable bill."
Otherwise, he said at the end of the video, "the next administration will have to deliver a COVID relief package".
"And maybe that administration will be me," he added, referring to his attempts to overturn the results of the presidential election that he lost to Joe Biden.
Mr Trump also complained about money in the bill for foreign countries, the Smithsonian Institution and fish breeding, among other spending.
As the COVID-19 death count rises amid a massive coronavirus resurgence that further threatens the world's largest economy, Republican and Democratic legislators finally hammered out a bill after months of wrangling and partisan finger-pointing.
Any delay in approving a deal would have dire consequences - it is meant to spare millions of jobless workers days away from seeing their unemployment benefits expire, and provide a new round of cash payouts.
Small businesses will benefit from more government grants, while the package also includes rental assistance and help to families facing eviction.
The massive package is part of a $2.3 trillion ($3.05 trillion AUD), almost 5,600-page "coronabus" bill that includes a so-called omnibus bill to fund the government for the coming year.
