Who cares how he learned about it? The President has hundreds, probably thousands of people asking him for stuff every day. He has teams of people who filter requests through the "appropriate means of communication."

Seriously, it's irrelevant. When he learned of a federally-controlled entity working against the best interests of Americans, he took action. That's really all that matters. I don't care if he saw a TV ad, a billboard, or any other unconventional means of communication with the US President.
