Following President Donald Trump‘s positive coronavirus test announcement early Friday morning, former New Jersey Governor Chris Christie said that nobody wore a mask in the prep room for Tuesday night’s debate.

Christie joined Good Morning America on Friday morning to discuss Trump’s interactions before his diagnosis and what precautions the Trump administration took to prevent the spread of the virus. He said that, although he was at the White House from Saturday until Tuesday’s debate, his last coronavirus test result—taken Tuesday morning—was negative.

“No one was wearing a mask in the room when we were prepping the president during that period of time,” Christie told GMA. “The group was about five or six people in total.”

He mentioned that the Trumps and Hope Hicks—a top advisor and trusted aide to the president who earlier tested positive on Thursday— “seemed completely fine” and that he did not notice any symptomatic people during the debate.

As he’s awaiting his test results from Friday morning, Christie said he isn’t experiencing any symptoms.
