Once a president has already decided that they are going to sign legislation, why not do it immediately?
For example, on Wednesday, March 10, the House of Representatives voted to pass the American Rescue Plan; which already passed in the Senate. This sends the bill to President Biden to sign into law. The White House has said that Biden plans to sign the bill into law on Friday (March 12).
Is there any reason that Biden does not sign the bill into law immediately; within hours after it passed in the House? Especially given that Biden's messaging around the stimulus / Covid relief has always been that there is no time to waste; and that it is urgent people people need the relief right now. So why delay the signing for 2 days? If Biden has already announced that he is going to sign it; why not just do it? Even if there are logistics issues with wanting the press and/or other VIPs to be present at the signing; could that not be arranged in less than a day?
I am using the American Rescue Plan as an example; but I mean to ask about legislation in general. Once a president has already decided that they are going to sign legislation, why not do it immediately?
