President Trump's health is under renewed scrutiny this evening, as his more-frequent-than-usual screenings seem at odds with his own proclamations of being in exceptional health.This morning, he got his fourth publicly announced exam of his second administration.Our White House correspondent, Liz Landers, is here with what we know and what we don't know about the health of the president.So, Liz, tell us about today's visit. What do we know?

Liz Landers:

The president was at Walter Reed medical facility for about 3.5 hours. He was also there, apparently, according to the schedule, to meet with troops and to speak with them as well.But this is the third medical checkup that he's had in about 13 months. He's also had a dental checkup a few weeks ago in Florida. This is the oldest president to ever be inaugurated. But listening to the president and his aides, he's constantly touting his vitality and his health.He said on TRUTH Social after his visit that he finished his six-month physical and that everything checked out perfectly. We have reached out to the White House to ask for a more detailed readout of what tests were done, what happened while he was there today. White House officials said that they are still working on it. We have not gotten that yet.But I did speak earlier today with former White House physician Dr. Jeffrey Kuhlman. He wrote a book on serving presidents. He served under Clinton, Bush and President Obama. And he said that most 80-year-olds go to the doctor frequently. President Trump is almost 80. So he said that this is likely related to his age and not necessarily to his position as the president.He also explained that a visit to Walter Reed is usually for more advanced medical checkups, like a colonoscopy, MRI, a CAT scan, things that you cannot do at the doctor's office within the White House. They do have that facility there, Amna, that allows for blood tests, he said, some kinds of dental checkups. And they can also do ultrasounds there as well.
