CHARLOTTE - Reports out of Charlotte say former NBC Nightly News anchor Tom Brokaw was rushed to the hospital Thursday morning after feeling light-headed and dizzy.

TMZ reports that the 72-year-old newsman, in North Carolina for the Democratic National Convention, had appeared on MSNBC's "Morning Joe" this morning when he began to feel ill.

NBC News President Steve Capus says, "On the set of 'Morning Joe' this morning, Tom Brokaw felt light-headed. Out of an abundance of caution, he was taken to a hospital and is being evaluated."

Around 9 a.m. Brokaw tweeted a message to fans seeking to assure them that everything is OK. It read "All is well Early AM I mistakenly took a half dose of Ambien and made less sense than usual. Made a better comeback than Giants."

Brokaw has been keeping a busy schedule of on-air appearances at the Republican National Convention last week and, this week, at the Democratic Convention.

He has served as special correspondent for NBC News since stepping down as anchor of "Nightly News" in 2004.
