Ken, Andy, and Sheila all pointed out this typo on NPR.org yesterday. Thanks, guys!
Where does NPR go wrong? It confuses the homophones "flack" and "flak." The headline is supposed to mean that a White House spokesperson said that President Obama was "obviously a Christian."
- flack (n.) - Press agent; spokesperson
- flak (n.) - Aircraft artillery; criticism
Correction: Obama 'Obviously A Christian': White House Flack
