WASHINGTON – President Donald Trump says he was aware of concerns about his health over the weekend but hadn't realized how dire the speculation had become.

Trump's public absence fueled online speculation about his health. His last public event was on Aug. 26, when he led a three-hour televised Cabinet meeting.

"And then I didn't do any (news conferences) for two days, and they said, 'There must be something wrong with him.' Biden wouldn't do them for months, you wouldn't see him, and nobody ever said there was ever anything wrong with him, and we know he wasn't in the greatest of shape," Trump said on Sept. 2 at an Oval Office press conference after being asked about the online speculation the following week.

The president participated in a sit-down, off-camera interview with The Daily Caller on Aug. 29 that lasted nearly an hour and visited his golf course, in Sterling, Virginia, three times over the Labor Day weekend. He did not interact with the press on any of the outings.
