Questions surround President Donald Trump's unscheduled visit to Walter Reed National Medical Center in Bethesda, Maryland on Saturday, Nov. 16.

Rumors are swirling that Trump, 73, was rushed to the hospital complaining of chest pain.

The White House released a statement saying Trump went to the hospital for a routine physical exam. But the report was quickly dismissed by Washington insiders.

"The one thing you can be absolutely sure of is this was not routine and he didn't go up there for half his physical," tweeted Joe Lockhart, a press secretary under President Bill Clinton.

Insiders whisper that Trump had a mild heart attack, and that he suffers from Angina, chest pain caused by narrowing of the arteries that feeds oxygen-rich blood to the heart muscles. Angina is a symptom of coronary artery disease.

If the president did suffer a heart attack, it was likely caused by the stress of the ongoing impeachment hearings on Capitol Hill in Washington, D.C.

Last week was tough for the real estate tycoon. Trump suffered a political defeat after his candidate for governor of Louisiana lost to sitting Governor John Bel Edwards in a state that Trump carried by nearly 20 percentage points in 2016.

And in another setback, Trump's friend and former advisor Roger Stone was found guilty on seven charges of lying to Congress, obstruction of Congress, and witness tampering. Stone faces a maximum of 50 years in a federal prison.
