Rubio had been talking to reporters in the hall about his concerns that China and other governments could demand social media platforms like Facebook and Twitter crack down on dissidents ahead of the Senate Intelligence Committee hearing.
GOP senator Marco Rubio was taking questions about Russian election interference on Capitol Hill on Wednesday morning when he was accosted by Infowars's tinfoil-hat-in-chief Alex Jones. "I'll take care of you myself".
Rubio eventually acknowledged him again, laughing he had a "heckler at a press gaggle", while again saying he didn't know who Jones was or about his website.
Things got even more tense when Jones put his hand on Rubio's shoulder, prompting a blunt reply from the one-time Presidential hopeful. "You are not going to silence me".
"Oh he'll beat me up", Jones retorted.
Jones proceeded to call the Cuban American politician "a little gangster thug".
Jones takes the comment and runs with it. Marco Rubio as the Florida Republican answered reporters' questions in a hallway. Jones retorts, "Look at this little frat boy".
Apple to unveil new iPhones in coming weeks
If previous years are any indication, Apple's new iPhones could go on sale the following week, perhaps on September 21. Apple's event comes a month after smartphone leader Samsung unveiled its latest flagship handset, the Galaxy Note 9.
Jones is the founder and host of InfoWars, a far-right website that peddles conspiracy theories.
So it shouldn't have been entirely surprising that Infowars host Alex Jones chose to stop by.
"Who's this guy, why are you platforming him?" At one point, Rubio told him to stop touching him after Jones patted him.
Jones was likely referring to his recent bans on platforms including YouTube and Facebook, which cited his hate speech and harassment as reason behind the censure.
When Rubio continues to ignore him, Jones calls out again, "I wonder why Rubio got so mad at me and threatened me physically". A second House hearing focused on Republican assertions that Twitter is censoring conservatives - a charge Jones has championed and the company has denied. After the hearing reconvened, he reportedly went back in to watch the testimonies. You are not going to silence America. "I'll take care of it myself", Rubio said.
Family members of some of the victims are suing Jones for defamation.
"You guys can talk to this clown", Rubio said to reporters as he turned and walked away.
