The White House press briefing on Tuesday was briefly interrupted by a medical emergency.

Press secretary Karine Jean-Pierre stopped a reporter in the middle of his question and rushed down from the podium to assist after a person declared, "We have an emergency!" 

"Hold on, did somebody pass out?" Jean-Pierre asked as White House medical staff attended to the individual, who appeared to have passed out due to the heat. 

After a few minutes, Jean-Pierre returned to the podium as the person in need received medical attention.

"Sorry about that. Hopefully she's okay," Jean-Pierre said. A reporter then made a comment about the heat, to which she replied, "You are correct. It is hot in here." 

Before resuming questions, Jean-Pierre asked the gathered White House correspondents if anyone needed water. The White House did not immediately respond to a request for comment about the individual's condition. 

Temperatures in Washington, D.C., hit a high of 92 degrees Tuesday but felt closer to 98 with humidity.
