Former President Donald Trump on Wednesday claimed during a border security event in Texas that President Biden would flunk a cognitive test. Trump said that he “aced” his own test, administered by then-White House physician Dr. Ronny Jackson, who is now a Texas Republican congressman. “[Jackson] did a test. Did I ace it? I aced it. And I’d like to see Biden ace it. He won’t ace it,” Trump said during a roundtable event at which he slammed Biden’s border policies. “He will get the first two. There are 35 questions and the first two or three are pretty easy. They are the animals. This is a lion, a giraffe. When he gets to around 20, he’s gonna have a little hard time. I think he’s gonna have a hard time with the first few, actually,” Trump added. Trump, now 75, made the 78-year-old Biden’s mental fitness a central issue in last year’s campaign, claiming that his challenger was mentally “shot” and too “sleepy” for office. #Biden #Trump #SleepyJoe The New York Post is your source for breaking news, news about New York, sports, business, entertainment, opinion, real estate, culture, fashion, and more.
