Glenn Greenwald told CNN's "Reliable Sources" on Sunday that he considers being condemned by Republican Congressman Peter King a "badge of honor."

King tweeted on Monday that "Awarding the Pulitzer to Snowden enablers is a disgrace," a reference to the Pulitzer Prize for public service journalism being awarded to the Washington Post and Guardian for their work publishing the NSA leaks provided by Edward Snowden.

Greenwald compared King's reaction to the pushback against Pentagon Papers leaker Daniel Ellsberg in 1971, saying that "if you want to be adversarial to those who wield power, you have to expect that those who wield power aren't going to like what you're doing very much."

Greenwald's initial reporting on the Snowden leaks was done at the Guardian (in tandem with the journalist Laura Poitras.) The Washington Post's Barton Gellman was also a lead reporter on the NSA leaks.

Greenwald described being awarded the Pulitzer as "really gratifying."
