A White House valet who traveled with the president last week and often works in the Oval Office tested positive for COVID-19 this weekend, according to administration sources familiar with the matter.

Valets are employees who typically serve the president lunch or bring him drinks upon his request.

Earlier this year, another valet who works in the Oval Office also tested positive.

Nine House Democrats representing Washington, D.C. and the city's Maryland and Virginia suburbs are calling on the White House to share more information about the White House coronavirus outbreak, which they're calling "out of control."

The lawmakers, whose constituents work at the White House, want the White House to disclose the date of Trump's last negative test, the total number of positive cases, and cooperate with local and state health departments' contact tracing efforts. 

"This is no time for publicity stunts that put people at risk, or for playing down the seriousness of this pandemic," they wrote in a statement Tuesday. "The American people will never trust the Administration to keep them safe if the White House cannot protect its own staff."

Facebook on Tuesday removed a post by the president, and Twitter tagged the post as misleading, after Trump incorrectly cited flu death numbers in a comparison to COVID-19.

Trump, the morning after returning from the hospital to be treated for COVID-19, tweeted, "Flu season is coming up! Many people every year, sometimes over 100,000, and despite the Vaccine, die from the Flu. Are we going to close down our Country? No, we have learned to live with it, just like we are learning to live with Covid, in most populations far less lethal!!!" he wrote.

A Facebook spokesperson said in a statement, "We remove incorrect information about the severity of COVID-19, and have now removed this post."

Twitter left the message up but covered it up with a message that said it violated the platform’s rules “about spreading misleading and potentially harmful information related to COVID-19."

According to CDC estimates, the annual flu death toll has ranged between 12,000 and 61,000 since 2010.

Trump also told Bob Woodward earlier this year that coronavirus is "more deadly than even your strenuous flu."

Trump used a similar comparison early on in the pandemic, before death totals began to rapidly rise.

On March 9, Trump tweeted, "So last year 37,000 Americans died from the common Flu. It averages between 27,000 and 70,000 per year. Nothing is shut down, life & the economy go on. At this moment there are 546 confirmed cases of CoronaVirus, with 22 deaths. Think about that!"

As of Tuesday, over 210,000 Americans have died from COVID-19.

The morning after leaving the hospital, Trump tweeted that he plans to attend next week's presidential debate in Miami.

The debate is set for Oct. 15 -- two weeks after the president tested positive for the coronavirus on Oct. 1.

When asked about the president campaigning, Trump’s physician, Dr. Sean Conley, said Monday, "As far as travel goes, we will see.”

Trump's campaign told ABC News on Monday that "it is the president’s intention to debate."
