I heard it on coasttocoastam last night. It's free streamlink week, so you can listen to it yourself. It's about 3:50 minutes into the first hour. However, as I listen to it again, it's clear I misheard the former president. I thought he said "I was convinced there was a UFO", but he actually said "I was convinced there wasn't a UFO". Sorry. False alarm.

Hey, I half asleep at the time.

He does say that scientists have recently discovered an Earth-like planet 20 million light-years away though!
