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.

The United Kingdom's Foreign Secretary on Saturday night said the government has "information that indicates the Russian Government is looking to install a pro-Russian leader in Kyiv as it considers whether to invade and occupy Ukraine."

Driving the news: U.S. National Security Council spokeswoman Emily Horne called the intelligence "deeply concerning" in a statement to Axios. The Biden administration has said Russia is actively manufacturing a pretext for invasion and warned that Putin could use joint military exercises in Belarus as cover to invade from the north.
