The White House on Saturday began checking the temperatures of anyone in close contact with President Donald Trump or Vice President Mike Pence.
White House staff met reporters at the door of the press briefing room with a thermometer, checking the temperatures of everyone coming in for a noon press conference on coronavirus developments.
"Out of an abundance of caution, temperature checks are now being performed on any individuals who are in close contact with the President and Vice President." White House spokesman Judd Deere said in a statement.
A man who appeared to be a journalist was blocked from entering the briefing room because his temperature was deemed too high.
Katie Miller, the press secretary for Pence, tweeted: "According to the White House Medical Unit, the temperature was taken three times over a 15 minute period - all three registered above the @CDCgov 100.4 guidelines."
The president later addressed the briefing room, saying had his temperature taken on his way into the room. Pence and the other administration officials at the lectern also confirmed they had their temperatures checked.
