CHARLOTTE, North Carolina (CNN) -- Former NBC news anchor Tom Brokaw, 72, was taken to the hospital Thursday morning while in Charlotte, North Carolina covering the Democratic National Convention.
A spokesperson with NBC said Brokaw felt "light-headed," and later Thursday, Brokaw said he "mistakenly took a half dose of Ambien," tweeting that it caused him to make "less sense than usual."
NBC News president Steve Capus said Thursday evening Brokaw was found to be "in great health."
"After medical evaluation and a round of tests, Tom was pronounced in great health and has been discharged," Capus said. "We're immensely grateful to the team at Carolinas Medical Center for their excellent care and professionalism."
After his appearance on "Morning Joe," the spokesperson said Brokaw was taken to a hospital "out of an abundance of caution."
A former anchor of NBC's "Nightly News," Brokaw now serves as a special correspondent for the network, where he reports and offers analysis for a variety of programs.
