David Bossie, who was recently tapped with overseeing the Trump campaign's legal challenges in the aftermath of Election Day, has tested positive for coronavirus, a person familiar with the matter confirmed Monday.

The campaign last week had reportedly tasked Bossie with leading efforts to pursue lawsuits in battleground states where President Trump was trailing President-elect Joe Biden. It's unclear how his diagnosis will impact that effort, which has largely been scattershot and marked by chaotic press conferences.

Bossie served as a deputy campaign manager during Trump's 2016 campaign and has remained an outside adviser in the four years since. He took on an increased role with the campaign in the closing weeks of the 2020 campaign and traveled with the president on some of his final rally trips.

Trump and his allies have alleged widespread voter fraud to claim the election was "stolen" by Democrats, but there is no evidence to support their claim. The lawsuits they have filed thus far have either been dismissed, would not change the result in the states where they are challenging the outcome or deal with process and not actual vote counts. 

Bossie is the latest Trump associate to contract the virus after Election Day. Others include White House chief of staff Mark Meadows, Housing and Urban Development Secretary Ben Carson and several other lower-level White House staff members.

Meadows and Carson were among those at last Tuesday's election night party at the White House, where dozens of guests mingled without masks. It was not immediately clear if Bossie was in attendance.
