The bill was passed with what lawmakers had thought was Trump's blessing, and after months of negotiations with his administration.
It was unclear what, if anything, Trump accomplished with his delay, beyond angering all sides and empowering Democrats to continue their push for higher relief checks, which his own party opposes.
In his statement, Trump repeated his frustrations with the COVID-19 relief bill for providing only $600 checks to most Americans instead of the $2,000 that his fellow Republicans already rejected.
Lawmakers now have breathing room to continue debating whether the relief checks should be as large as the president has demanded.
Aside from unemployment benefits and relief payments to families, money for vaccine distribution, businesses and more was on the line.
