Your comment made me realize I didn't know. So I looked this up, and it's actually a bit of both. It depends on if Congress is in session when the 10 days have passed:
If any Bill shall not be returned by the President within ten days (Sundays excepted) after it shall have been presented to him, the same shall be a Law, in like manner as if he had signed it, unless the Congress by their Adjournment prevent its return, in which case it shall not be a Law.
How do you propose to build a widespread movement (not just people on Lemmy and Reddit) without trying to inform them about the issues with Flock and similar tech?
The general public has to understand what's even going on before enough people will care to vote differently or pressure public figures to do actually change it.
Nobody is saying this week of action is the final step and once it's over, no one will do anything else about this.
