It was a while ago. But late last century the "line item veto" which allowed presidents to get rid of things in bills they didn't like was rejected by the courts. Oddly Reagan (R) asked for this power initially, but Clinton (D) ended up getting it.

"Congress granted this power to the president by the Line Item Veto Act of 1996 to control "pork barrel spending", but in 1998 the U.S. Supreme Court ruled the act to be unconstitutional in 6–3 decision in Clinton v. City of New York.

The court found that exercise of the line-item veto is tantamount to a unilateral amendment or repeal by the executive of only parts of statutes authorizing federal spending, and therefore violated the Presentment Clause of the United States Constitution. Thus a federal line-item veto, at least in this particular formulation, would only be possible through a constitutional amendment. Prior to that ruling, President Clinton applied the line-item veto to the federal budget 82 times."
