DES MOINES, Iowa — Republican Tim Pawlenty says his presidential campaign will tell the American people the truth and suggests that President Barack Obama doesn’t.

The former Minnesota governor released an Internet video Sunday ahead of a public appearance Monday in Iowa, where he planned to formally enter the race for the 2012 GOP nomination.

Pawlenty said in the video what aides already had disclosed, saying, “I’m running for president of the United States.” He said the country needs a president who will tell the American people the truth about the severe challenges facing the country and how America can get back on track.

Pawlenty said, “President Obama won’t do that. I will.”

He adds, “Together, we will change this country, and this time it’ll be for the better.”
