(Columbia-AP) Governor Mark Sanford is threatening to veto parts of the state budget that a conference committee is working on today. Sanford wrote lawmakers late last week, outlining his concerns. He's worried that not enough money is going to restore the state's reserve funds or trust funds that have been raided to balance the budget for the past three years.

Sanford also says the General Assembly should not be counting on 90 million dollars from increased tax collection enforcement. He is concerned because much of that money is being set aside to pay for several of his Cabinet agencies.

Sanford says if the spending plan lawmakers are expected to approve this week doesn't address the concerns, he may have no choice but to veto all or substantial parts of the budgets.
