Beloved newsman Tom Brokaw has spoken out to assure fans he is OK after he was admitted to the hospital on Thursday.

The 72 year old was taken away in an ambulance after feeling light-headed on the set of TV series Morning Joe in Charlotte, North Carolina.

However, the former anchor of NBC Nightly News has since taken to and blamed the health scare on a sleeping medication mix-up, writing, "All is well. Early AM (morning) I mistakenly took a half dose of Ambien and made less sense than usual."

Brokaw has been in Charlotte to cover the Democratic National Convention.
