If the White House wants to get a message out, how do you go about doing that? Apparently the answer to that question is now: have Ashton Kutcher twitter about it.
Seriously.
The White House wanted to get the word out about National HIV Testing Day. So what did they do? They contacted Ashton Kutcher. The guy has over 2.5 million followers on Twitter. So they asked him to tweet about National HIV Day.
