Eminem has always gotten attention for his controversial lyrics but recently it was taken to an entirely new level. New documents reveal that the "Rap God" musician, whose real name is Marshall Mathers, was investigated by the Secret Service after an alert by a TMZ staffer.

In August 2018, Eminem announced that he would be releasing a new album called "Kamikaze," only eight months after his previous outing, "Revival." The new project was led by the track "The Ringer," which quickly grabbed the attention of fans due to his claim that he was visited by Secret Service members.

"'Cause Agent Orange just sent the Secret Service / To meet in person to see if I really think of hurtin' him / Or ask if I'm linked to terrorists / I said, 'Only when it comes to ink and lyricists,'" the rapper stated in the lyrics.

According to BuzzFeed News, fans were correct in their speculation that there was truth behind the song in question. After the Secret Service refused to publicly state whether they had in fact spoken with the "8 Mile" actor, the publication opted to file a Freedom of Information Act request in order to see what really took place.

Now, thanks to 40 pages of documents, it has been proven that the 47-year-old's account was factual.

On Dec. 15, 2017, the day "Revival" was released, a "concerned citizen" reported the musician's song "Framed" to the agency. This was due to "an inappropriate comment towards President Donald Trump and a threatening comment towards Ivanka Trump."

As for who was behind the reporting, the documents also revealed that an unnamed TMZ employee had alerted the Secret Service to the existence of the lyrics in an email. Along with a link to an article in the Hill regarding the content of the song, they wrote, "I want to know if your agency is investigating Eminem for his threatening lyrics about First daughter Ivanka Trump."

Per BuzzFeed News, it has been suspected that the employee was looking to obtain a comment on any ongoing investigation, but it remains unclear if they received any reply.

Furthermore, the obtained documents noted, "This is not the first time MATHERS made threatening comments towards POTUS and his family. In June 2017, MATHERS freestyled comments that were threatening in nature towards POTUS."

Eventually, after a background check, an interview took place on Jan. 16, 2018 with both Eminem and his legal team present. Even though they are heavily redacted, the pages reveal that the conversation revolved around the rapper's BET freestyle and lyrics in both "Framed," which included the line about Ivanka Trump, and "Like Home."

Two days later, they determined the case would be "non-referred" to a federal prosecutor.
