2009: Secretary Clinton to Mexico: Who painted your virgin?

We understand that Sec Clinton had a difficult and embarrassing incident in Mexico City.

Here is the story: Hillary Clinton leaves flowers for Our Lady of Guadalupe, asks ‘Who painted it?’

A few minutes later, Sec Clinton told Mexicans: “you have a marvelous virgin!”

Is this like the "reset" button that she gave the Russian foreign minister?

Didn't some "expert" at The State Dept tell Sec Clinton that it's "a divine image" not some Mexican "Mona Lisa"?
