President Donald Trump suggested on Tuesday he may take action against the “treasonous” New York Times for publishing a negative report on his health.

“The New York Times, and some others, like to pretend that I am ‘slowing up,’ am maybe not as sharp as I once was, or am in poor physical health, knowing that it is not true, and knowing that I work very hard, probably harder than I have ever worked before,” Trump said in a lengthy message on Truth Social. “I will know when I am ‘slowing up,’ but it’s not now!”
