Bachmann: 2012 plans to be decided by 'early summer'

Rep. Michele Bachmann, R-Minn., says she'll decide on a run for president by "early summer".

The Republican head of the House Tea Party Caucus Tuesday morning told CNN she isn't ready to say she's "jumping in" or out. Bachmann said the candidate who represents the Republican Party likely will be decided by voters in four early-primary states.

"We need a nominee who really understands the times that we live in, who knows what to do in response to that, and has the political courage to do what has to be done," Bachmann said. "Very tough decisions will be made, and I think our nominee needs to be willing to be a one term president if that's necessary to get the job done."

Bachmann has criticized President Obama's policies since he took office in 2008.

However, she said she agrees with the president's decision to resume military trials for detainees at Guantanamo Bay, Cuba. Obama campaigned against that Bush-era policy before winning the White House.
