“Anticipating a very busy 2020, the President is taking advantage of a free weekend here in Washington, D.C.," Grisham said.

The president left the White House by motorcade at 2:15 p.m., according to pool reports, arriving at Walter Reed at 2:47. He left the medical center at 5:03 p.m., arriving back at the White House at 5:41.

Before leaving Walter Reed, Trump met with the family of a special forces soldier injured in Afghanistan, Grisham said.

Grisham appeared on Fox News' "Justice with Judge Jeanine" later Saturday, seeking to quash rumors on social media that the president could be in ill health.

"He's healthy as can be," Grisham said. "He’s got more energy than anybody in the White House."

Later on Twitter, Grisham said any speculation is "wholly irresponsible & dangerous for the country."

Trump tweeted shortly after midnight about his visit to Walter Reed.

"Visited a great family of a young man under major surgery at the amazing Walter Reed Medical Center," Trump tweeted. "Also began phase one of my yearly physical. Everything very good (great!). Will complete next year."

Trump had his last physical in February. The White House issued a broad statement then saying the president was “in very good health,” but gave few details about the 73-year-old’s health.

In 2018, then-White House physician Rear Adm. Ronny Jackson praised Trump’s health during a White House briefing, saying he was in “excellent health” and could “live to be 200 years old.”

Jackson also said he wanted Trump, who was then 6 feet, 3 inches tall and weighed 239 pounds, to lose “10 to 15 pounds.”
