The attempted assassination of former President Donald Trump on Saturday was not the only such effort to murder a president, former president, or presidential candidate in recent memory.

Fellow presidential contender Robert F. Kennedy Jr, whose father was infamously slain during an event at the Ambassador Hotel in California while campaigning for president in 1968, has been no stranger to extreme danger on the campaign trail.

Kennedy was quick to issue a statement on X following the assassination attempt.

“Now is the time for every American who loves our country to step back from the division, renounce all violence, and unite in prayer for President Trump and his family,” Kennedy posted.

Kennedy suffered three serious security breaches; still, the Biden administration continues to deny him a Secret Service detail.

The first incident happened when a man dressed as a federal marshal attempted to muscle his way up to Kennedy during an event in California last year. The man was heavily armed, but he was intercepted by Kennedy’s private security detail after they identified irregularities with his credentials.

The Los Angeles District Attorney’s Office declined to file felony charges against the man, deciding instead to slap him with misdemeanors, according to ABC News. This legal action resembled law enforcement actions that enabled other security breachers for Kennedy.

In another scary moment for Kennedy, a 28-year-old real estate agent, identified as Jonathan Macht, was arrested for breaking into Kennedy’s home on October 27, 2023. He was taken into police custody and released the same day. He then returned to Kennedy’s home and breached the perimeter again. He was again arrested.

“Yesterday an intruder climbed the fence at my home and was arrested,” Kennedy wrote on X at the time. “After being released from police custody later in the day, he immediately returned to my home and was arrested again.”

Kennedy and his wife were home at the time of both incidents. Gavin de Becker & Associates, the private company responsible for Kennedy’s security, had repeatedly warned the Secret Service about Macht, according to Politico.

The denial of Secret Service protection to a major presidential candidate this late in a campaign is unprecedented in recent political history and has drawn the ire of officials like Sen. Ted Cruz (R-TX), who has slammed Homeland Security Secretary Alejandro Mayorkas for not approving Kennedy’s requests.

Sen. Bernie Sanders (I-VT), for example, was granted a detail in February 2016 despite not being a party nominee and not having won a single primary at the time of his request.

The incidents involving Kennedy were preceded by a plot against former President George W. Bush’s life in February 2022. An alleged ISIS operative identified as Shihab Ahmed Shihab was intercepted by the FBI as he allegedly surveilled Bush’s Dallas-area home.

FBI documents obtained by NBC News claimed he planned to have ex-Iraqi intelligence officials aid his plot to murder the former president.

The Secret Service was seemingly not involved in resolving these incidents that endangered the lives of some of America’s most prominent political figures.

Relatedly, Rep. Bennie Thompson (D-MS) introduced legislation in April to deny Secret Service protection to anyone convicted of a felony. Though the bill did not pass, it appeared to target Trump, who had a looming criminal conviction in New York at the time.

Thompson fired a staffer on Sunday after the staffer allegedly tweeted, “I don’t condone violence but please get you some shooting lessons so you don’t miss next time ooops that wasn’t me talking,” after news broke of Trump’s attempted assassination.
