Arianna: Stewart, Colbert 'Speaking Truth To Power' (VIDEO)

Amid plenty of laughs about the "Rally to Restore Sanity" and HuffPost's "Sanity Bus," there was also some serious discussion on "Hardball" about what happened this Saturday on the National Mall.

Arianna and Salon's Steve Kornacki joined host Chris Matthews on Sunday to reflect on the previous day's festivities.

"The kind of stuff that Jon Stewart and Colbert do is not candy," Arianna said in response to possible criticisms of the event and its audience. "It's speaking truth to power. For me, it's really the best of satire that goes back to Jonathan Swift and Mark Twain."

The conversation then turned to the core message of the event -- working together -- and to the role and responsibilities of modern media.
