What it does
A plain-language summary is coming. Here is the official summary from the Congressional Research Service:
Moving Americans Privacy Protection Act This act revises requirements regarding the public disclosure of personally identifiable information contained in the manifest of vessels or aircraft entering a U.S. port or place. Specifically, the act directs U.S. Customs and Border Protection (CBP) to remove such information, including Social Security numbers and passport numbers, from a manifest signed and transmitted to CBP before it is accessible by the public.
How Congress voted
This law passed by voice vote or unanimous consent, so there is no record of how individual members voted.
