Liz Cheney might have challenged Enzi for his “go along, to get along” personality in the Senate, but the three-term senator is joining the effort to defund Obamacare promoted by Sens. Mike Lee, R-Utah, Ted Cruz, R-Texas, Rand Paul, R-Ky., and Marco Rubio, R-Fla.

Enzi gave a speech against Obamacare on the Senate floor on Thursday and signed the Senate letter circulated by supporters of the bill.

“U.S. Senator Mike Enzi, R-Wyo., will not support a continuing resolution that funds further implementation or enforcement of Obamacare,” Enzi explained in a statement highlighting his support of the idea.

The letter of support is also signed by Sens Inhofe, R-Okla., Vitter, R-La., Thune, R-S.D., Chiesa, R-N.J., Fischer, R-Neb., and Grassley, R-Iowa.
