Presumptive Republican presidential candidate Mitt Romney is pulling out the big guns in an effort to catch up with President Barack Obama's fundraising.

The Wall Street Journal reported on Monday that former Vice President Dick Cheney will host a July 12 fundraiser for the GOP hopeful in Jackson Hole, Wyoming.

During his 2008 campaign, Romney spoke out in favor of the enhanced interrogation techniques supported by Cheney during President George W. Bush's administration. In a 2007 Republican primary debate, Sen. John McCain (R-AZ), who now supports Romney, blasted the former Massachusetts governor for refusing to say that waterboarding was torture.

"I'm astonished you would think such a torture would be inflicted on anyone we held captive and anyone could believe that that's not torture," McCain told Romney. "It's in violation of the Geneva Conventions, it's in violation of existing law. And, governor, let me tell you, if we're going to get the high ground in this world and we're going to be the America we have cherished and loved for more than 200 years, we're not going to torture people."

"I do not say that I am in favor of torture," Romney shot back. "I am not going to specify the specific means of what is and what is not torture so that the people that we capture know what things we are able to do and what things we are not able to do."

Last year, Romney spokesperson Andrea Saul clarified that the candidate did not believe waterboarding was torture.

At an event in April after getting a new heart, Cheney encouraged Republicans to unite around Romney.

Last year, Romney said Cheney was "the kind of person I'd like to have" as vice president.
