Former New Jersey Gov. Chris Christie (R) tweeted Saturday that he has checked himself into a hospital as a "precautionary measure" after testing positive for the coronavirus.

The big picture: Christie attended an indoor briefing by President Trump in the White House on Sept. 27, and helped the president prepare for Tuesday's debate. He also attended Judge Amy Coney Barrett's Rose Garden formal nomination on Sept. 29, which saw multiple politicians close to the White House test positive for COVID-19.

  • Christie's diagnosis follows a flurry of positive COVID-19 tests from White House officials, Republican congressmen and others close to the Trump administration, following Trump's positive test.

What he's saying: "In consultation with my doctors, I checked myself into Morristown Medical Center this afternoon. While I am feeling good and only have mild symptoms, due to my history of asthma we decided this is an important precautionary measure, Christie tweeted.

  • "I am thankful for our hardworking medical professionals and look forward to coming home soon," he added.

Every available piece of data proves it: The coronavirus pandemic is getting worse again, all across America.

The big picture: As the death toll ticks past 212,000, at a moment when containing the virus ought to be easier and more urgent than ever, we are instead giving it a bigger foothold to grow from.

If the U.S. death rate had matched that of other wealthy countries, between about 55,000 and 215,000 Americans would still be alive, according to a scathing new analysis by Columbia University's National Center for Disaster Preparedness.

Why it matters: These countries have taken a significantly different approach to the virus than the U.S., providing yet another example that things didn't have to be this way.
