Sen. Jim DeMint (R-S.C.) hit back at President Obama Thursday for suggesting that Republicans are violating Grover Norquist’s tax pledge by opposing the extension of tax credits for the renewable energy industry.

“What the president is doing is wrong, and again, it is hypocritical,” DeMint said during a conference call with reporters. “He doesn’t go after the green companies that he’s given these big energy subsidies to that end up with credits for years to come.”

DeMint, a favorite of Tea Party activists, joined Rep. Mike Pompeo (R-Kan.) and Norquist, the powerful president of Americans for Tax Reform, to rebut Obama’s claims and push for the elimination of a slew of energy industry tax credits.
