Trump Posts Escalating AI Videos in Canada Border Feud.

Trump posted an AI-generated video Saturday depicting an army of armed, blond-coiffed Canada geese guarding 'Lake America.' He labeled the birds 'Donald Ducks.'

• The 34-second clip is set to the 'Hawaii Five-O' theme song.
• 50 percent U.S. tariffs hit roughly $20 billion in Canadian exports on August 22.
• Canada retaliated with tariffs of up to 50 percent on U.S. goods.
• Trump signed an executive order Thursday directing federal agencies to call Lake Ontario 'Lake America.'

Why it matters: The president can direct how federal agencies refer to geographic features but cannot compel foreign governments, U.S. states, or private entities to do the same.

• Canadian Prime Minister Mark Carney noted the name Lake Ontario derives from a Wendat word more than 400 years old, predating both nations.
• Rep. Stephanie Bice (R-OK) said the renaming 'does not help the case' for Republicans.
