On Monday, based on some random information he found on Wikipedia, Rush Limbaugh called President Obama's decision to deploy military advisers to Africa—part of an effort to combat the Lord's Resistance Army—a plot to "wipe out Christians." Limbaugh failed to note that the LRA is infamous for raping and murdering civilians, and although he noted the error the next day, he claimed he'd just learned of the atrocities. On tonight's Report, Stephen Colbert explained Limbaugh's actions: "That's why it's called research; if you do it before, it's called pre-search."
