For months, President Donald Trump has treated the coronavirus as a threat the country is close to putting behind it.

He has pushed for businesses and schools to reopen, repeatedly predicted the virus would disappear, questioned the value of widespread mask use and continued holding large political events where masks and social distancing were often the exception rather than the rule.

Just five days ago, Trump stood in the White House Rose Garden and declared that the country was “rounding the corner” on the pandemic.

Tonight, the president is hospitalized with COVID-19.

And an outbreak is spreading through the White House, Trump's campaign and the Republican political establishment.

At the center of the growing concern is another Rose Garden gathering — the September 26 ceremony announcing Judge Amy Coney Barrett as Trump's nominee for the Supreme Court.

The event was supposed to showcase one of Trump's most consequential achievements.

Instead, one week later, it is under intense scrutiny as a possible source of a widening coronavirus outbreak.

A Celebration With Few Masks

Approximately 150 people gathered at the White House for Barrett's nomination ceremony.

The photographs from that afternoon are striking.

Rows of guests sat closely together in the Rose Garden. Few wore masks. People shook hands, hugged and mingled with one another.

Trump stood alongside Barrett and members of her family.

Inside the White House, guests also gathered for receptions.

The precautions recommended to millions of Americans — masks, distancing and avoiding crowded gatherings — were largely absent.

The White House relied heavily on rapid coronavirus testing to protect the president and those around him.

That strategy now appears anything but foolproof.

The List Keeps Growing

President Trump has tested positive.

First Lady Melania Trump has tested positive.

Former White House adviser Kellyanne Conway has tested positive.

Republican Sen. Mike Lee of Utah has tested positive.

Republican Sen. Thom Tillis of North Carolina has tested positive.

University of Notre Dame President John Jenkins has tested positive.

Former New Jersey Gov. Chris Christie has tested positive and announced Saturday that he has checked himself into a hospital.

A journalist who attended the event has also tested positive.

All were present at the September 26 ceremony.

It remains unknown whether the virus spread at the Rose Garden event itself, at associated indoor gatherings or elsewhere.

But with multiple attendees now infected, the gathering has become a major focus for public-health officials trying to understand how the outbreak spread.

The Virus Trump Has Repeatedly Downplayed

The outbreak carries an unmistakable irony.

Trump has spent much of the pandemic arguing that Americans should return to normal life.

He has repeatedly resisted wearing a mask in public.

During Tuesday night's presidential debate, Trump mocked Democratic nominee Joe Biden's frequent mask use.

“I don't wear masks like him,” Trump said.

“Every time you see him, he's got a mask.”

Three days later, Trump was admitted to Walter Reed National Military Medical Center with COVID-19.

The president's own doctors said Saturday that he is receiving treatment with remdesivir after previously receiving an experimental antibody cocktail.

His chief of staff, Mark Meadows, said Trump's vital signs during the previous 24 hours had been “very concerning.”

The virus Trump has repeatedly suggested the country is close to defeating has now reached the president himself.

A White House That Operated Differently

For months, the White House has operated differently from much of the country.

While businesses installed plexiglass barriers, families canceled weddings and funerals, sporting events emptied their stadiums and Americans were urged to remain six feet apart, events at the White House frequently continued with large crowds and limited mask use.

Administration officials have pointed to frequent testing as a reason those precautions were less necessary around the president.

But coronavirus tests provide information about a person at a particular moment.

They do not prevent infection.

And they do not guarantee that someone infected recently will immediately test positive.

The Rose Garden ceremony is now providing a stark demonstration of that limitation.

Contact Tracing Questions

The outbreak is also raising questions about the White House's efforts to identify and notify people who may have been exposed.

Guests from the Barrett ceremony have since traveled back across the country.

Trump himself continued traveling during the days following the event.

He attended a campaign rally in Pennsylvania, participated in Tuesday's presidential debate in Cleveland, traveled to Minnesota for another campaign event and attended a fundraiser Thursday in Bedminster, New Jersey.

The Washington Post reports that there is little evidence the White House has provided comprehensive contact-tracing guidance to the hundreds of people who potentially crossed paths with Trump and other infected officials.

Some attendees at the Barrett ceremony say they have received no contact from the White House.

A Very Different Picture One Week Later

On September 26, the Rose Garden looked almost like a place where the pandemic didn't exist.

People sat shoulder to shoulder.

They hugged.

They shook hands.

Most didn't wear masks.

The president stood before the crowd and celebrated his Supreme Court nominee.

Seven days later, the picture could hardly be more different.

The president is in Walter Reed.

The first lady is infected.

Two United States senators are infected.

A former White House adviser is infected.

The president of Notre Dame is infected.

Chris Christie is infected and hospitalized.

And health officials are trying to determine whether the White House itself became the center of an outbreak.

For months, Trump has insisted America is turning the corner on COVID-19 and has often behaved as though the precautions recommended by public-health officials were unnecessary around him.

On October 3, the coronavirus is delivering a very different message — from inside the White House itself.
