A news reporter suffered the beginnings of a stroke live on air, leaving her struggling to read the teleprompter.
Julie Chin, a reporter with NBC affiliate KJRH of Tulsa, in Oklahoma, was reporting on Nasa's Artemis I rocket when she became unable to speak.
She later explained on Facebook that it "seemed to have come out of nowhere", but within minutes she lost partial vision in one eye before her hand and arm went numb.
Chin said she knew she "was in big trouble" when her mouth "would not speak the words that were right in front of [her] on the teleprompter".
The reporter's coworkers called 911 and Chin went to the hospital where she underwent tests. Chin revealed that the doctors believe she had the beginnings of a stroke, but not a full stroke.
Although she said "there are still lots of questions", she reassured her fans that she "should be just fine".
