Yes, this is a new thing, using the signing statement/line item veto to eliminate or add what he doesn't want. I don't remember any pres doing this, ever, even Nixon.
IMO, this is unConstitutional. Here's what Constitution states:
U.S. Constitution - Article 1 Section 7Article 1 - The Legislative Branch
Section 7 - Revenue Bills, Legislative Process, Presidential Veto
All bills for raising Revenue shall originate in the House of Representatives; but the Senate may propose or concur with Amendments as on other Bills.
Every Bill which shall have passed the House of Representatives and the Senate, shall, before it become a Law, be presented to the President of the United States; If he approve he shall sign it, but if not he shall return it, with his Objections to that House in which it shall have originated, who shall enter the Objections at large on their Journal, and proceed to reconsider it. If after such Reconsideration two thirds of that House shall agree to pass the Bill, it shall be sent, together with the Objections, to the other House, by which it shall likewise be reconsidered, and if approved by two thirds of that House, it shall become a Law. But in all such Cases the Votes of both Houses shall be determined by Yeas and Nays, and the Names of the Persons voting for and against the Bill shall be entered on the Journal of each House respectively. If any Bill shall not be returned by the President within ten Days (Sundays excepted) after it shall have been presented to him, the Same shall be a Law, in like Manner as if he had signed it, unless the Congress by their Adjournment prevent its Return, in which Case it shall not be a Law.
Every Order, Resolution, or Vote to which the Concurrence of the Senate and House of Representatives may be necessary (except on a question of Adjournment) shall be presented to the President of the United States; and before the Same shall take Effect, shall be approved by him, or being disapproved by him, shall be repassed by two thirds of the Senate and House of Representatives, according to the Rules and Limitations prescribed in the Case of a Bill.

The veto power in the United States Constitution was derived from the British method of Royal Assent. On April 5, 1792 President George Washington vetoed a bill designed to apportion representatives among the several states. This is the first time the presidential veto was used in the United States. The Congress first overrode a presidential veto on March 3, 1845.

Line-item vetoTypically, a veto applies to an entire piece of legislation. Some states in the United States have granted their governors the additional power of a line-item veto. This allows them to veto or "cross out" only certain parts of the legislation, while allowing the rest to pass. Although details vary, it is not uncommon for a piece of legislation that has undergone a line item veto to be returned to the legislative body for final approval; they can either accept the amended legislation or decide not to pass it at all in its new form. The line item veto power has been controversial. Perhaps its most famous abuse was when Governor of Wisconsin, Tommy Thompson, crossed out individual letters in a bill so that the remaining words comprised entirely different sentences, effectively introducing a new provision into the bill. Some states permit line item vetoes only in "appropriation bills," or bills granting money for the various government departments. The United States Congress passed a law authorizing the President to strike out up to three items of appropriation in a single bill, but the Supreme Court ruled this procedure unconstitutional in Clinton v. City of New York 524 U.S. 417 (1998).
