Ryan, R-Wis., told CBS' "Face the Nation" Sunday his party's presumptive presidential nominee had been specific about his economic strategy since the primaries, which went a long way to putting him on the brink of the nomination.
"He was more specific than anybody running for president about specifically what he would do to prevent a debt crisis to create jobs, to reform the tax code, to reform these entitlement programs from bankruptcy," Ryan said.
Ryan dismissed the idea Romney had few ideas outside lowering taxes for big business and the rich.
"Mitt Romney has put out more specifics on reforming the tax code, cleaning up the corporate system, getting rid of special interest loopholes, lowering rates to 25 percent on the corporations," Ryan said. "He has put out more specifics on how to reform entitlement programs, to saved Medicare from bankruptcy, to cut government spending, to reduce the deficits than Barack Obama and the United States Senate has."
