It now heads to President Biden's desk, where he is expected to sign it on Friday according to White House spokeswoman Jen Psaki.
No Republicans voted for the stimulus.
In a Wednesday afternoon statement, President Biden - or whoever wrote it - said: "Now we move forward" with the legislation, which includes $1,400 for eligible residents in lieu of the long-promised $2,000 payments. The statement confirms a Friday signature.
The stimulus is expected to be signed into law before various federal benefits expire on March 14, after which $1,400 checks can begin flowing within one to two weeks based on the timeline for the previous round of checks, and Tuesday comments by Senate majority leader Chuck Schumer (D-NY), who said at a Buffalo, New York press conference that families could expect to receive checks in about two weeks.
