Trump COVID-19 updates: Top Trump aide Stephen Miller tests positive

The office of the first lady issued a statement Tuesday detailing the COVID-19 precautions in the "Executive Residence," which is part of the White House where Trump and the first family live.

"Staff wear full PPE and continue to take all necessary precautions, which include updated procedures to protect against cross contamination," the first lady's chief of staff, Stephanie Grisham, said in a statement.

"Residence staff in direct contact with the First Family are tested daily, with support staff tested every 48 hours," the statement continued.

The office said that since March, they've used "hospital-grade disinfection policies, had White House Medical Unit lead coronavirus workshops so staff could have their concerns addressed, significantly reduced staff, and encouraged maximum teleworking."

Grisham declined to tell ABC News if household staff were being given the option not to come in to work while the president and first lady were in isolation or whether staffing was reduced or staggered. Members of the first lady's office have been working from home, Grisham told ABC News.

The vice commandant of the Coast Guard, Adm. Charles Ray, is under quarantine at home after testing positive for COVID-19 on Monday, according to a Coast Guard statement.

Ray had "mild symptoms over the weekend," the Coast Guard said.

The Coast Guard said it's "following established policies for COVID, per CDC guidelines, to include quarantine and contact tracing."

All the members of the Joint Chiefs of Staff are now quarantining at home after Ray tested positive, a U.S. official confirmed.

The official says this is being done as a precautionary move after Ray participated in a meeting with the chiefs either Friday or Monday. All have tested negative so far, according to a senior defense official. The only member of the Joint Chiefs who is not quarantining is the Marine Corps Commandant because he was traveling overseas at the time of the meetings.

A Department of Defense statement says, "Out of an abundance of caution, all potential close contacts from these meetings are self-quarantining and have been tested this morning. No Pentagon contacts have exhibited symptoms and we have no additional positive tests to report at this time.""

The Department of Defense added, "There is no change to the operational readiness or mission capability of the U.S. Armed Forces. Senior military leaders are able to remain fully mission capable and perform their duties from an alternative work location."

Amid questions about whether Vice President Mike Pence should be quarantining following his contact with Trump last week, Pence's physician issued a memorandum saying Pence "is not a close contact with any individuals who have tested positive for COVID-19, including President Donald J. Trump and senior members of the White House administration, according to the guidelines of the Centers for Disease Control (CDC)."

Pence's last known interaction with Trump was one week ago on Tuesday, ahead of the president's trip to Cleveland for the presidential debate.

Pence was also at the White House Rose Garden for Amy Coney Barrett's Supreme Court nomination; 11 people at that event have since tested positive for COVID-19.

Pence is now in Utah ahead of Wednesday night's vice presidential debate.

Pence's doctor said the vice president has had daily rapid tests and periodic PRC tests.

Pence and his wife tested negative for the coronavirus again on Tuesday morning, the vice president's office said.

The president is reporting no symptoms from the coronavirus on Tuesday, Trump's physician, Dr. Sean Conley, said in a memorandum.

"This morning the President’s team of physicians met with him in the Residence. He had a restful first night at home, and today he reports no symptoms," the memo said. "Vital signs and physical exam remain stable, with an ambulatory oxygen saturation level of 95-97%. Overall he continues to do extremely well."
