Sarah Huckabee Sanders actually said...
Dr. Jackson has been a White House physician for the last 12 years, trusted by Presidents Bush, President Obama, and now President Trump. He is the only doctor that has weighed in on this matter that has actually examined the President. And so I think a doctor that has spent the amount of time with the President as Dr. Jackson has is not only the most qualified but the only credible source when it comes to diagnosing any health concerns.
