Deputy Secretary of State Wendy Sherman tested positive for COVID-19 over the weekend, she announced Monday.
"I'm experiencing mild symptoms and will be working remotely from home per CDC guidance," she tweeted. "I am thankful to the @StateDept MED team for taking excellent care of me and all our colleagues around the world during this pandemic."
Secretary of State Antony Blinken and Sherman were together for a meeting with Saudi Arabia’s deputy minister of defense in Washington, D.C., on Saturday.
It was initially unclear how frequently Sherman is testing, or if she is considered a close contact by Centers for Disease Control and Prevention standards to anyone currently in the delegation overseas.
