Giuliani's son, a White House staffer, tests positive for coronavirus

Andrew Giuliani, the son of the president's personal attorney and a staffer at the White House, tested positive for coronavirus, he tweeted Friday.

"I am experiencing mild symptoms, and am following all appropriate protocols, including being in quarantine and conducting contact tracing," Giuliani tweeted.

Giuliani, a special assistant to the president, is the latest White House staffer to test positive for the highly contagious virus in recent weeks. He has worked as a liaison to sports leagues and had a prominent role promoting Trump's support of bringing back college football this fall.

Giuliani held a combative press conference on Thursday in which he made baseless and at times conspiratorial claims alleging the election was stolen from Trump. He referenced the film "My Cousin Vinny" at one point, and black streaks ran down his face from his hair as he spoke.

The press conference was held indoors in a cramped space. Neither Giuliani nor any of the attorneys standing near him wore masks.
