The ILLICIT CASH Act, sponsored by Mark Warner (D-VA) and co-sponsored by 11 Senators (6 R, 5 D), has been included in the National Defense Authorization Act (NDAA).
https://www.congress.gov/bill/116th-congress/senate-bill/2563 This bill would ban anonymous shell companies in the United States, which are commonly used as means of laundering money from illicit activities. This bill was originally introduced in 2019, but its insertion into this year's NDAA makes for an interesting twist.
President Trump has publicly stated that he would veto the NDAA unless Section 230 of the CDA were repealed, but given his (and his organization's) history with money laundering and/or launderers, it wouldn't surprise me if this particular bill is his actual reasoning for threatening to veto the NDAA. It may not be his rationale, but there's a "follow the money" aspect to this that can't be ignored.
There's also a massive archive of information regarding FinCEN files/data which has been compiled by BuzzFeed News, the ICIJ, and hundreds of journalists from around the world. A lot of this data circles around anonymous shell companies, as well as public info. It's a massive rabbit hole.
