The latest example was Vice President Mike Pence's chief of staff Marc Short, and reportedly several of his aides, testing positive for Covid, swelling the list of administration staff to have caught the virus.
Vice President Mike Pence has been declared an "essential worker" and will continue on the campaign trail despite a coronavirus outbreak in his office, the White House says. After campaign events, Pence typically would do regional media interviews with local television reporters, but the aide said those have been canceled since Short's positive COVID-19 test.
"Today, Marc Short, Chief of Staff to the Vice President, tested positive for COVID-19, began quarantine and assisting in the contact tracing process", Pence's press secretary Devin O'Malley said in a statement.
In an appearance on the CNN programme "State of the Union", Mr Meadows on Sunday cited the "essential personnel" distinction for Mr Pence as justification for the vice-president not adhering to CDC guidelines for isolation after potential exposure to an infected person.
The new infections offered a reminder of the way Mr. Trump and his allies have downplayed the advice of public health experts to wear masks and observe social-distancing guidelines to combat COVID-19 transmission.
US infectious disease expert Anthony Fauci said on Sunday that it would be clear whether a COVID-19 vaccine was safe and effective by early December but that more widespread vaccination would not be likely until later in 2021.
Biden and Harris have been hammering Trump over his handling of the pandemic, which has seen the USA suffer roughly one-fifth the world death total though its population is only four percent the total.
Pence will not quarantine.
"President Trump has accomplished more in 47 months than Joe Biden has in 47 years of failure", Murtaugh added.
Thousands of supporters have been attending President Donald Trump's campaign rallies in the final weeks of the presidential election.
Coronavirus: No new Covid-19 community cases on Sunday
Senator John Barrasso of Wyoming said that citizens need to remain vigilant because the virus isn't going away anytime soon. This metric indicates a warning when the weekly number of deaths increases more than 20% for two consecutive weeks.
The U.S. recorded its highest one-day number of new COVID-19 infections Friday at more than 83,000 - more than 6,000 higher than the country's previous record set in July.
The plan for Pence largely underscores the cavalier approach to the coronavirus the Trump campaign has taken throughout the election season, even after the president, his wife and son tested positive.
Meadows said Mr. Pence would continue to campaign and speak at rallies.
After visiting North Carolina later Sunday, the vice president is traveling to Minnesota on Monday and back to North and SC on Tuesday.
"I'm not saying he is not campaigning", Meadows said.
"He's waved the white flag on life".
Biden went on to bash Trump's characterization of himself as a "wartime president" who is "fighting a war against an invisible enemy" early on in the pandemic.
Harris, speaking shortly after arriving in Detroit, said that Meadows' comments to Tapper on Sunday show the Trump administration is "admitting defeat".
Democratic presidential nominee Joe Biden echoed that sentiment in a statement later Sunday, saying that Meadows "admitted this morning that the administration has given up on even trying to control this pandemic, that they've given up on their basic duty to protect the American people". The state has asked the FBI to investigate the fire that was set around 4 a.m.in a ballot drop box outside the Boston Public Library downtown, Massachusetts Secretary of the Commonwealth William Galvin's office said.
