Many close to Marilyn Monroe in the early 1960s claim she was head over heels in love with President John F. Kennedy during their love affair. But the latest episode of “The Killing of Marilyn Monroe” podcast reveals how the actress’ scandalous romps with the politician led to the FBI and CIA’s infiltration into her personal life.

Episode five of the 12-part series, featured above, unmasks the great lengths America’s most-sought-after actress took to win over JFK’s attention. Entertainment journalist Charles Casillo claimed the actress didn’t just want the former president’s attention, she needed it.

“It took on a very, very deep significance to her. It wasn’t just a fling or a love affair, or, ‘Let’s explore this to see where it goes,’” Charles claimed in episode five. “It was more, like, you have to love me.”

JFK would later use his need for a “squeaky-clean image” as an excuse to pass Monroe off to his brother and attorney general at the time, Bobby Kennedy, Casillo revealed. But both married men ultimately kicked her to the curb.

“These were political animals. They couldn’t fall for her! So when they started distancing themselves from her, she was really, really lost,” Casillo continued.

But the blonde bombshell refused to take “no” for an answer. In a desperate attempt to get through to the Kennedy brothers, Monroe left a scathing voicemail to the U.S. Department of Justice threatening to tell-all.

Hollywood historian Bill Birnes revealed explosive details of Monroe’s phone call that the U.S. government agencies tampered with.

“’If you don’t return my phone call,’ she says, ‘I’m going to go public with these affairs!’” Birnes claimed Monroe shouted over the phone.

“Unbeknownst to Marilyn Monroe, both the CIA and FBI had taped her phone. She was wiretapped. Both agencies had recordings of Marilyn’s threat to Bobby Kennedy,” Birnes furthered.

As Radar readers know, the blonde bombshell had several other trysts with high-profile men, including singer Frank Sinatra. Despite reaching the peak of her career, “The Killing of Marilyn Monroe” revealed the actress suffered from depression and suicidal thoughts, causing Sinatra to never marry her.

Actor Gianni Russo claimed to have witnessed the actress’s abuse of drugs and alcohol reach “alarming levels” after her fling with Sinatra introduced her to the country’s most powerful mob bosses.

Chicago mob boss Sam Giancana “drugged her up,” Russo claimed in the episode.

“They passed her around,” Russo explained, adding, “They just used her as a rag doll at bars and clubs and plays with her.”

Biographer Danforth Prince concluded that Monroe’s attraction to high-profile men was no coincidence. The troubled actress’s involvement with the mob, Sinatra, and the Kennedys led to the FBI and CIA’s interest in following her every move.

“She got involved with the Kennedys. Who hated the Kennedys? Sam Giancana hated the Kennedys. So, by getting to Marilyn, it was an open door to anyone who wanted to punish the Kennedys,” Prince claimed.
