Pawlenty: It was 'proper' to have Karl Rove at Romney retreat

Former Minnesota Gov. Tim Pawlenty (R) on Sunday denied that it was wrong for Mitt Romney to invite Republican strategist Karl Rove to a recent retreat with top donors.

Karl Rove's Crossroads America -- a Super PAC -- and its sister organization, Crossroads GPS, have spent millions of dollars on ads attacking Democrats. Super PACs can raise an unlimited amount of money to influence federal elections, but are not allowed to coordinate directly with candidates.

"It is indeed proper because the line between the campaigns and these independent groups is that you can’t coordinate about the expenditure of money," Pawlenty said on CBS News' Face the Nation. "So you can talk all day long about issues, policy, general things like that. You just can’t cross the line to say, ‘now, you’re going to spend your money this way and we’re going to spend our money that way.’"

"It’s a little bit of an oversimplification, but that’s the line and it certainly wasn’t cross here nor will it be during this campaign."
