(CNN) After touting Keegan-Michael Key's support for Pete Buttigieg, the campaign told CNN later Saturday that the actor will now appear at the Buttigieg campaign events simply to encourage early voting and voter registration -- not officially endorse the former South Bend, Indiana, mayor as the Democratic candidate for president.

"Keegan-Michael Key will be attending events this weekend, including Pete's rally tomorrow, to encourage early voting and voter registration across the state in advance of the Nevada caucuses," Buttigieg spokesman Chris Meagher said in a statement, adding: "Pete's campaign is excited for the voter registration support Mr. Key brings, although Keegan-Michael has not officially endorsed any candidate."

The campaign first told CNN that Key was set to announce his support for the former mayor in Nevada, appearing at early voting locations Saturday before joining a canvass kick off in Las Vegas, and introducing Buttigieg on stage at the rally. The campaign later walked back the support comment and said Key has not officially endorsed any candidate.

"With his extraordinarily diverse skill set and wide-ranging talent in both comedy and drama; Emmy and Peabody Award-winning writer, actor, and producer Keegan-Michael Key is one of Hollywood's most in-demand forces," the Buttigieg campaign told CNN earlier Saturday.

Key isn't new to politics.
