Alex Jones is a talk show host, and a self proclaimed libertarian. His YouTube channel touts him as, "a prominent figure of the 9/11 Truth Movement." He runs two websites: infowars.com and prisonplanet.tv
Note that in the video, he references the Drudge Report as his primary source.
Some choice quotes:
"Well, the Trayvon Martin case, that's been promoted by Jesse Jackson, Al Sharpton, others, has completely collapsed - and appears to be a hoax."
"It looks like Mr. Zimmerman followed him, and that was his only mistake."
"Why is it always okay to call white people names?"
"[...]tens of thousands of people - in Orlando, in Dallas, in Chicago, in New York - come out and protest in basically a, 'Hate White People Event.'"
