On his Fox News show this evening, Glenn Beck blamed a purported suppression of history for his research staff's inability to find footage of Sen. Robert Byrd filibustering the Civil Rights Act. Watch:

BECK: At the same time this was going on, Robert Byrd was filibustering the Civil Rights Act. Why is it this guy dies and we haven't seen any footage -- Tiffany, did we look for footage? We're still looking. We can't find footage of the filibuster of the Civil Rights Act of this guy. How? How is that possible? How did the guy die when one of the most important things the guy did in his life, at least in the first 47 years, was to filibuster the Civil Rights Act? We have re-written history, and we are only looking now for the truth that helps our side. It must stop.

Uh, Glenn? The reason your staff can't find that 1964 footage is that it doesn't exist, because television cameras wouldn't be allowed into the Senate chamber for another ten years. According to senate.gov:

Following succession to the presidency after the resignation of Richard Nixon in 1974, Gerald Ford nominated Nelson Rockefeller as vice president, as prescribed by the Twenty-fifth Amendment to the U.S. Constitution. Rockefeller took the oath of office in the Senate chamber on December 19, 1974. Television cameras that had been recently installed in the Senate chamber in anticipation of a possible impeachment trial of Richard Nixon were instead used to televise the swearing in of Vice President Rockefeller. This marked the first time television cameras had been allowed in the Senate chamber.

By the way, it took me less than thirty seconds to find that information. I did a Google search for “history of cameras Senate floor.” It was the second result.

Don't forget, Beck says he has “some of the biggest minds in America” on his research team “working harder than ... any staff ever on television.”
