Donald Trump’s tiredness, recent MRI and hand bruise suggest he may be taking medication to treat Alzheimer’s disease, according to a “curious” California Democrat.

Rep. Sydney Kamlager-Dove, D-Calif., tweeted that Trump is showing signs he’s taking the Alzheimer’s disease drug Leqembi.

“The Alzheimer’s drug Leqembi:- Is administered through an infusion (for example, through the hand)- Can cause swelling, bleeding, or fluid leakage in the brain, requiring regular MRIs- Can cause tiredness,” Kamlager-Dove tweeted along with a picture of Trump’s hand bruise. “Curious.”
