After gaining access to the PAM DB system for payments, DOGE members at the Treasury department discover what appear to be payments flowing to recipients without Social Security numbers. Other recipients appear to be dead.

Although he was considered more friendly to the Trump admininstration and DOGE, Andrew DeMello, the acting general counsel for the IRS refuses to turn over the addresses of 7.3 million taxpayers that had been requested by ICE.

However, IRS is still building this system and is targeting a late July launch date.
