President Donald Trump spent the early-morning hours digging up years-old dirt on his newest political enemy and bashing him on social media.

Wes Moore of Maryland has become the latest Democratic governor to take on Trump over his partisan gerrymandering and threats to deploy National Guard troops to blue states, inviting the president last week to walk the streets of Baltimore with him.

Trump responded over the weekend with a social media rant in which he threatened to pull federal funding from Baltimore, leading the governor to mock the president’s physical ability and lack of military service. In response, Trump made the bizarre claim on Monday that the governor had called him the “greatest president of my lifetime” when they met in 2024.

On Wednesday, Moore slammed Trump’s “absolutely comical memory”—a comment that apparently left the 79-year-old president still smarting hours later.
