"I've been saying for quite some time now, when he was candidate Joe Biden, that I didn't think that he had the cognitive ability to do the job," said Jackson. Additionally, Jackson emphasized that Biden has "degenerated" over the last three years. "He's got these people that surround him that are inappropriately encouraging him to continue to run because it builds up who they are and what they do. But our border, our wars overseas, our economy, you know, it's just a disaster right now. And he just can't do the job. And it's just on display every day that he's not capable of doing this job anymore," Jackson warned.

Trump-backed candidate Dr. Ronny Jackson reacts to the big win in Texas and says wearing a mask amid COVID-19 should be a'personal choice' instead of a mandate. Dr. Ronny Jackson, the incoming Texas congressman and former White House physician to President Trump, called out the left for failing to demand a rigorous cognitive screening for President-elect Joe Biden, saying "there's something going on" with the Democrat's mental acuity. Jackson, in Washington for congressional orientation, recalled to Fox News this week the intense pressure he faced to administer a cognitive test to Trump as pundits and mental health professionals openly speculated that the commander-in-chief could have early-stage dementia or a decline in mental health. Trump scored a perfect 30 out of 30 during the cognitive test as part of his annual physical and Jackson announced the results in 2018 at a White House press conference, where he also famously quipped that Trump might "live to be 200 years old." Now Jackson, a retired Rear Admiral in the U.S. Navy, is raising the alarm about the "huge double standard" of the press for not demanding the same type of screening for Biden, who would be 78 at the inauguration.
