David Bossie, who was tapped just days ago to cope with President Donald Trump's efforts to question the presidential election results, tested positive for the coronavirus on Monday, according to NBC News.
As a result, Bossie is no longer part of the campaign process decision-making process "because he cannot be at campaign headquarters or the Oval Office," a source told NBC News.
Bossie's diagnosis leaked hours after news that Trump-appointed Housing and Urban Development Secretary Ben Carson was positive about Covid-19 and days after it was revealed that White House Chief of Staff Mark Meadows was positive about the virus .
Two sources speaking to NBC News said Bossie tested positive for Covid-19 on Sunday.

The other source said Bossie is probably home and feeling fine.
Bossie attended a Republican Party of Arizona press conference on the Trump campaign in Phoenix last Thursday.
At this event, Bossie, who was not wearing a mask, stood next to US Representatives Paul Gosar and Debbie Lesko, both Republicans from Arizona, State Party leader Kelli Ward, former Trump campaign officials Jeff DeWit and Boris Epshteyn, and the former US representative John Shadegg.
Lesko spokeswoman Rachel Harris told NBC News that Congressional doctor treating Lesko said she didn't need to do a quarantine or Covid test.
Lesko has no symptoms of the virus, Harris said.
Trump is campaigning in several states to legally challenge ballot papers and to re-count ballots in a number of states. Bossie was appointed to lead this effort on Friday, three days after election day.
Former Vice President Joe Biden was forecast to be the election winner on Saturday by NBC News and other major media outlets.
Trump, a Republican diagnosed with coronavirus in October, has refused to allow the election.
Bossie, who was Trump's 2016 deputy campaign manager, has been blamed for campaign efforts by current campaign manager Bill Stepien and senior White House adviser, Jared Kushner, Trump's son-in-law.
Bossie is the head of the conservative advocacy group Citizens United.
The White House declined to comment, and the Trump campaign did not immediately respond to a request for comment on Bossie when contacted by CNBC.
