"If there is such evidence, put it on the table, put it out in front of the media, put it in front of the judicial process or the legislative review process so people can kick the tires and see if it's real or not," Pawlenty says. "Until then it really just looks like a game."

Turning to the 2014 midterm election cycle, Pawlenty, now CEO of the Financial Services Roundtable, said he thinks odds favor the GOP to win back a Senate majority.
"The Republicans have a very good chance actually of taking the Senate, although it's going to be close," Pawlenty said. "The message needs to be jobs and economic growth," said the former two-term Minnesota governor.
"What do you need to do to get jobs growing and get this economy ignited. Get the message around that and by the way be on the side of small businesses and entrepreneurs and I think that's the winning message."
