His Twitter feed is uncensored and some argue his comments can go too far. In fact, a few of Sabo’s recent tweets struck a nerve and got the attention of the United States Secret Service. One of the tweets involved bringing back Lee Harvey Oswald as a zombie.

Here are some other controversial tweets from Sabo:

The above tweets were part of the reasons why, on Tuesday, Sabo returned home and found a calling card from a Secret Service agent.

Sabo called the agent listed on the door hanger and scheduled a meeting at his home for 10 a.m. on Wednesday.

Before the interview, Sabo posted the above image and alerted his Facebook friends and Twitter followers about the pending visit.

Shortly after the Secret Service visit, Sabo posted a video that claims to cover most of the entire interview. Sabo told TheBlaze there was a little more to it, but “I just wanted to get it out.”

The Secret Service has confirmed that they interviewed Sabo, though they would not provide additional information about the visit.

According to the note left on the doorknob, the agents were coming to talk to the artist about “possible I.D. theft.”

During the brief exchange, the agents asked, Sabo questions like; ”Did you send out the tweets about bringing back Lee Harvey Oswald as a zombie?” To which the artist responded, “How likely is that going to happen?”

Sabo did admit to sending the three tweets in question.

“I realize we have a f***head in the White House and the Constitution no longer means s**t, but as far as I’m concerned we still have the First Amendment, correct?” he said, sitting behind a desk featuring Obama’s face painted on toilet seat covers.

The two agents agreed with him about the First Amendment, but cautioned him about “language that starts advocating violence,” calling it a “grey area the First Amendment doesn’t cover.”

Sabo stressed that his posts were political speech and “obviously not” advocating violence. However, he also added that he hopes President Obama’s “plane crashes.”

Following the Secret Service interview, Sabo posted this tweet.

Sabo also called into TheBlaze Radio’s “Morning Blaze” on Wednesday to discuss the upcoming Secret Service visit (The interview with Sabo begins at the 1:14:00  mark of the recording):
