NEW: Trump has pardoned Binance founder CZ, wiping away one of the US’s most significant crackdowns on crypto crime.
The pardon is emblematic of Trump’s approach to clemency:
CZ hired lawyers & lobbyists with Trump ties, while Binance struck a business deal with the Trump family’s crypto company.

the president using the office to punish americans that didnt vote for him should really be one of the biggest scandals in americas history
Trump is upfront in saying he will use the shutdown to punish Democrats, and here are the receipts. About $27.2 billion cut from Dem districts compared to about $0.7 billion in GOP districts.
