Andrew Giuliani, Trump's special aide and the son of lawyer Rudy Giuliani, infected with nCoV after a press conference to denounce election fraud.

"I have mild symptoms and adhere to all the appropriate standards, including isolation and contact tracking," Andrew said on Twitter on November 20, after announcing that he had the test results.

Mr. Rudy Giuliani, 76, and Jenna Ellis, another top Trump campaign attorney, had negative results.

"The entire legal team will continue to follow doctors' recommendations and standards", Ms. Ellis said.

Andrew coordinates sports activities at the White House for an annual salary of $ 95,000, according to government documents.

A Trump campaign official said Andrew wore a mask while sitting in the audience seat watching a press conference hosted by his father at the Republican National Committee headquarters in Washington on Nov. 19.

At the nearly two-hour event, Mr. Giuliani and other Trump campaign attorneys made long speeches without a mask, as they continued to accuse a "systematic conspiracy" by dozens of officials.

However, they did not provide any evidence to support this allegation, other than a few testimonies by those who claimed to have witnessed suspicious behavior by election officials.

More than 30 people involved in the White House and the events held there have been positive for nCoV over the past few months, including Trump, wife Melania, son Barron, press secretary Kayleigh McEnany and chief of war.

On November 20, a spokesman for Donald Trump Jr., the US President's eldest son, also said he was positive for nCoV since the beginning of the week and is on quarantine, but has no symptoms.
