Sen. Mike Enzi, R-Wyo., will be the new Senate Budget Committee Chairman, after Sen. Jeff Sessions, R-Ala., announced Wednesday he would end his own bid for the chairmanship.

Enzi is well-known for introducing the Marketplace Fairness Act, which would enable states to collect sales tax from online retailers. Enzi also introduced legislation to permanently repeal the death tax and supports reforming Social Security to fix its finances.
