MADISON, Wis. (AP) — Gov. Scott Walker says repealing Wisconsin's minimum mark-up on gas sales wouldn't satisfy his conditions for raising the state's gas tax to help pay for road construction.

Republicans have been wrestling among themselves over how to solve a $1 billion shortfall in the state's transportation fund. Walker has proposed borrowing money and delaying work on major projects. Assembly Speaker Robin Vos believes every way to raise revenue should be considered, including raising the gas tax.

Walker has said he'll veto any increase in the gas tax without a corresponding tax decrease somewhere else. On Monday, he told reporters during a news conference detailing his visits last week to Middle Eastern military bases that erasing the state's minimum mark-up law on gas doesn't count as a corresponding tax decrease.
