Top Trump aide Stephen Miller has tested positive for the novel coronavirus.

He is married to the vice president's communications director, Katie Miller, who tested positive in May and was one of the first aides in the White House to contract the virus.

With the addition of Stephen Miller, it now means six out of the nine attendees in the Trump debate session from last Monday have tested positive.

“Over the last five days I have been working remotely and self-isolating, testing negative every day through yesterday," he said in a statement. "Today, I tested positive for COVID-19 and am in quarantine.”

Two members of the White House press shop and a military aide have tested positive for COVID-19, bringing the number of cases with ties to the White House to 23 so far, according to a tally by ABC News.

Harrison Fields, assistant press secretary, and Jalen Drummond, deputy assistant press secretary, bring the total number of White House press shop members to test positive for the virus to five, ABC News has learned.

U.S. Coast Guard Lt. Cmdr. Jayna McCarron also tested positive for COVID-19 over the weekend, ABC News confirmed. McCarron traveled with President Trump on Thursday to a campaign event in New Jersey.

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."
