Known as one of Donald Trump's top aides, Stephen Miller on Tuesday revealed that he had tested positive for COVID-19. Serving as a senior adviser to the president and with a comprehensive portfolio in the White House, he joins the first lady Melania Trump, campaign manager, press secretary, party chair, counselor, and several other staffers who have contracted coronavirus.

Trump spent his first full day at the White House after staying at Walter Reed National Military Medical Center for 3 days to get treated for the disease. Miller's wife, Katie Miller is the communications director for Vice President Mike Pence and was one of the earliest Trump aides to contract coronavirus, back in May. The couple is expecting their first child.

Miller released a statement noting that he has been working remotely and self-isolating over the last five days and has tested negative every day through yesterday. He went on to reveal that he had tested positive for COVID-19 and was in quarantine.

Before joining the Trump campaign in 2016, Miller worked as the communications director for then-Senator Jeff Sessions and is the president's loudest voice in the White House when it comes to restricting immigration, which is his main policy concern. Miller has built up close working relationships with West Wing colleagues, particularly with Trump's son-in-law and senior adviser Jared Kushner.

The West Wing, especially the press office has recently transformed into a coronavirus hot spot, with press secretary Kayleigh McEnany, counselor Hope Hicks, and four of McEnany’s aides testing positive for COVID-19 in the last week. Nearly 31 people connected to the president have tested positive for coronavirus recently, POLITICO reported.

Miller accompanied Trump and Hicks on Air Force One during the president's Minnesota campaign trip. Officials told CNN that Hicks complained about feeling sick while on the flight back to Washington following a fundraiser and campaign rally that took place at the Land of 10,000 Lakes. She isolated in a different cabin as soon as she began showing symptoms.

Miller's wife and Pence's communications director Katie Miller tested negative for coronavirus on Tuesday morning. She had traveled to Salt Lake City with Pence ahead of vice presidential debate which is slated to take place on Wednesday, but left the trip Tuesday of caution, according to an official.

Current CDC (US Centers for Disease Control and Prevention) guidelines on possible reinfection state that people who recovered from the disease do not need to be tested or quarantined for about three months after their last positive test.
