US President-elect Joe Biden has warned of “devastating consequences” if President Donald Trump continues to delay signing a Covid-19 economic relief bill into law.
Unemployment benefits and a ban on evictions will be affected unless the bill is signed by the end of Saturday.
The package worth $900bn (£665bn) was approved by Congress after months of difficult negotiations and compromises.
Mr Trump says he wants to give people bigger one-off payments.
The bill includes the payment of $600 to Americans earning less than $75,000 a year. Mr Trump says he wants Americans to receive $2,000 but Republicans in Congress have refused to agree to the change.
The coronavirus economic relief comes with a $1.4tn federal budget attached. A partial government shutdown will begin on Tuesday unless legislators pass a stopgap bill before then – but this would not include coronavirus aid and Mr Trump would still have to sign it.
