I know for a fact that California has "line-item" veto. Not sure if that's the same thing as item veto. Hope this helps : )
Line-item veto
The line item veto has little chance of passing.
An item veto means power to reject particular parts, or items, of a bill.
The line item veto is used only in budget bills
yes he does as well as the pocket veto
ho- the US president does not have a line-item veto. He must either veto the whole bill or let it go either with his signature or not.
item veto
Line-item veto.
When a Governer approves parts of a bill and vetos others, it is called using a "line item veto."
The two types of veto that can be carried out by the president are the "Pocket Veto" and the "Regular Veto." The Pocket Veto is where the president is given a bill, but fails to sign it within the ten days of the adjournment of Congress. The Pocket Veto is less common. The Regular Veto is one in which the president returns the bill back to Congress, with a message explaining his problems, reasons for return, and recommendations for revision. From there Congress may or may not fix it depending on it's actual importance.
