WASHINGTON (CNN) - Democratic presidential candidate Dennis Kucinich caused heads to turn earlier this week when he acknowledged he once saw a UFO.
But if elected to the White House, Kucinich wouldn't be the first president to have such an encounter.
"When I was back as a peanut farmer in southwest Georgia, I and about 25 others saw something in the air that changed colors and was round and came and left," former President Jimmy Carter said in an interview with CNN’s John Roberts on American Morning. "We couldn't figure out what it was."
But while he couldn't identify the object, Carter said he doesn't think it was space aliens.
"It was unidentified as far as we were concerned, but I think it's impossible in my opinion, some people disagree, to have space people from other planets or other stars to come to us - I don't think that's possible," he said.
At Tuesday's presidential debate, NBC’s Tim Russert asked Kucinich, a congressman from Ohio, about a recent account from actress Shirley MacLaine that he saw a UFO at her home in Washington State.
“It was an unidentified flying object, OK? It's, like, it's unidentified. I saw something," Kucinich responded.
