I think Trump is going to announce his DOJ is doing a major bullshit investigation of some dem. It'll be one of Trump's low ever-on-the-boil bête noires. Biden? Obama? Less likely because it's the afternoon and not prime time is that his DOJ is doing a major bullshit investigation of something involving voting like "millions and millions of illegals are voting and I'm stopping them."

Edit. If it's voting or whatever - I expect some "official" follow up today or tomorrow probably as a speech by the AG.
