Saying it was probably Hunter Biden is the easy, predictable joke, even though it's virtually impossible it was him since why would Hunter use the West Wing visitor entrance to see his father at the White House. Saying it was Joe or Jack Smith is simply insane and turns what could have been potentially a minor political liability for the White House into just another crazy bullshit thing Trump said that Republicans have to pretend they didn't see him post on Truth Social.
"Where are the White House SECURITY TAPES, like the ones I openly and happily gave to Deranged Jack Smith, which will quickly show where the Cocaine in the White House came from??? They already know the answer, but probably don't like it!" Trump later posted to Truth Social.
