This should be the sticking point to invoke the 25th. Officials need to be loud and make a stink about how Trump can’t tell fact from clear fiction and therefore cannot perform the duties of the office. Make the people of America see the image on the news everyday and make those on his side say out loud if they think it’s fake or real. Half of the masses will never be convinced that he lacks the morality to lead until they’re already in his camps. This is the earliest clear as day moment to act on that which cannot be held to subjective scrutiny or partisanship.
The real reason he will justify this bullshit like that is because he has to admit hes racist otherwise, “if hes brown I want him gone from my town” basically. Ask him if we should be deporting white right wing gang members based on their tattoos and show him cropped photos of Hegseths tats.
