As part of his campaign rollout Monday, Tim Pawlenty published an op-ed in USA Today that was one part biography, one part attack on President Obama.

Pawlenty was also on the early morning TV shows, and his Twitter account tweeted a picture of the former Minnesota behind an Iowa caucus sign. "Enjoyed talking to the morning anchors this morning about my campaign," he wrote.

After his speech at 11:30 a.m. in Des Moines, Pawlenty will go on Rush Limbaugh's radio show this afternoon.
