New podcast claims to present evidence of who really killed JFK

Director Rob Reiner and journalist Soledad O'Brien claim they have evidence of who really killed President John F. Kennedy in Dallas 60 years ago.

Why it matters: Reiner and O'Brien co-host a new 10-part podcast series called "Who Killed JFK?" The show promises to solve what Reiner calls America's most famous murder mystery through interviews with authors, witnesses, CIA officials and forensic experts.

State of play: Reiner, who directed "When Harry Met Sally" and "The Princess Bride," says he has evidence that U.S. government officials, including at the CIA, were behind the plot to murder the president and that President Johnson participated in covering up the conspiracy.

• O'Brien, who's hosted shows on CNN, MSNBC and NBC, lends an air of journalistic credibility to the show.

Details: The podcast's second episode dropped yesterday. It's available wherever you get your podcasts.

Reality check: Obviously Reiner and O'Brien aren't the first dilettante detectives who've delved into the JFK assassination. And from the trailer and first episode, released earlier this month, the show seems to take an "Only Murders in the Building" approach.

• Yes, but: We'll still listen.
