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? The president was at Walter Reed medical facility for about three and a half hours. He was also there apparently, according to this 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

AIDS, 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 Kulman. 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, an MRI, a CAT scan, things that you cannot do

at the doctor's office within the White House. They do have that facility there, Omna, that allows

for blood tests, he said, some kinds of dental checkups, and they can also do ultrasounds there as well.

So what did Dr. Coleman say he would be looking for if he were President Trump's doctor?

Dr. Coleman said that he has three main things that he's looking for.

Here's what he told me earlier today.

Specifically for an 80-year-old president, advanced age is by far the number one concern.
