Cruz, Iowa governor trade jabs over renewable energy

Republican presidential candidate Ted Cruz and Iowa governor Terry Branstad traded criticisms Sunday over Cruz's opposition to renewable energy subsidies, which could play a major role in Monday's caucuses in the state.

"Cruz's voting record has been against ethanol," Branstad said during a panel on Iowa politics on "Fox News Sunday." "It's been against the tax credit for wind energy, and those are thousands of jobs in our state."

Branstad, also a Republican, has declined to endorse any candidate but encouraged Iowans to vote against the Texas Republican because of his stance on subsidies. "We've got a lot of really great candidates and most of them support renewable energy," he said Sunday.

Separately, in an appearance on NBC's "Meet the Press," Cruz accused Branstad of being compromised on the issue by his financial interests.
