During his syndicated radio show this afternoon,Rush Limbaugh suggested that Newtown shooter Adam Lanza must have been a liberal because he was “mentally disturbed” before sarcastically taking back the remark because “that’s one of those things you just can’t tell the truth about.”

A female caller asked if Limbaugh knows Lanza’s political orientation. Limbaugh noted that, in the past, shootings have always been politicized, citing ABC reporter Brian Ross‘s false accusation that Aurora, Co., shooter James Holmes was a Tea Party member.
