I'm not a big fan of Breitbart, but this hilarious. I checked all of the links provided and they are still there except for the Daily Kos link.
From the article:
"On September 21st, the SEIU website published this statement about the free bus rides...We'll provide the buses to and from the event in most metropolitan areas within 12 hours of Washington, D.C."
"The Pittsburgh Branch NAACP will host two buses to take us to the march. The buses are "FREE"!!!...We are also providing a "free" lunch."
