As if this day isn’t crazy enough with impeachment news and a plunging stock market, the 2020 Election had a significant development:

Sen. Bernie Sanders, 78, was hospitalized in Las Vegas.

“During a campaign event yesterday evening, Sen. Sanders experienced some chest discomfort. Following medical evaluation and testing he was found to have a blockage in one artery and two stents were successfully inserted,” said Sanders’ senior adviser Jeff Weaver on Wednesday in a statement.

“Sen. Sanders is conversing and in good spirits. He will be resting up over the next few days,” Weaver said. “We are canceling his events and appearances until further notice, and we will continue to provide appropriate updates.”

Sanders remains hospitalized, a source told ABC News.

Weaver led an all-staff phone call this morning to inform the entire campaign, according to a source familiar with the call. An additional source familiar described the call as subdued.

I am using the word “heart attack” — the media seems to be avoiding that word.

In any event, even if he stays in the race, it will raise questions about his health. Obviously.
