Giuliani and the others filing the suit argued—as opponents of the veto had for many years—that the Constitution required the president to either sign, veto or allow a bill to become law without his signature. The Constitution, they said, did not allow him to veto parts of a bill.
The Supreme Court agreed and in June 1998, ruled that the line item veto was unconstitutional. Giuliani argues that he favors the line item veto and believes the Constitution should be amended to allow it, but he said the power cannot be created by passing a simple law.
Romney is correct that Giuliani is guilty of having filed the lawsuit that killed the line item veto. But Romney neglects to say that Giuliani had several accomplices along with him.
