Although much has been made of the optics and the fact of the confrontation between Democratic Congressman Keith Ellison and Sean Hannity, much less attention has been paid to the substance of Ellison's allegations. For one thing, it bears emphasizing that the video that set off Ellison was a mashup video, obviously designed to put President Obama in as negative a light as possible, presented by Hannity as an introduction to their discussion. But more important were Ellison's allegations that Hannity has a long history of making truth secondary to his political agenda. Media Matters came up with ten examples of Hannity falsehoods. I found several more.

In Media Matters' list, my "favorites" are Hannity's deliberate promotion of birtherism (while, in another falsehood, pretending otherwise) and fueling the "Obama is a secret Muslim" meme. But there are many, many more. Here are some of my own "favorites:"

Hannity promoted the baseless theory that Obama would start a war with Iran in order to win re-election.

Hannity insisted he never questioned President Obama's patriotism.

Hannity repeatedly hypes phony links between Obama and Louis Farrakhan in order to paint them as racial soulmates.

Hannity repeatedly insisted Democratic criticisms of the Iraq war were harming our troops, even though Geneal Tommy Franks figures told him otherwise.

And last but not least: Hannity promised he'd undergo waterboarding for charity in order to prove it's not torture.
