President Trump required personnel at Walter Reed National Military Medical Center to agree to non-disclosure agreements in 2019 before he'd agree to be treated at the facility, per NBC News.

Why it matters: Trump sought coronavirus treatment at Walter Reed this weekend after his positive test on Thursday evening. But officials in the Trump administration and within Walter Reed offered conflicting information on the president's health, fluctuating between calling his symptoms "mild" and "very concerning."

• NBC notes that "four people familiar with the process did not know whether, during the president's most recent visit over the weekend, he had the same requirement for Walter Reed staff members who had not previously been involved in his care."

Between the lines: The president's health information would already be protected by HIPAA.

• But Trump has a history of NDAs, often making his employees and personal acquaintances sign them during his career as a businessman.
