Homeland Security Secretary Kristi Noem was transported by ambulance on Tuesday to a hospital in Washington, DC, after an allergic reaction, the Department of Homeland Security said.

“Secretary Noem had an allergic reaction today. She was transported to the hospital out of an abundance of caution. She is alert and recovering,” said DHS spokeswoman Tricia McLaughlin.

CNN observed several Secret Service agents posted at several entrances outside the emergency room at the hospital where the secretary was admitted.
