He can veto it, but he won't have to. The Senate is controlled by his party, and Mconnell has shown time and again he won't stand up to the president (he won't agree with him either, but will use it politically for his own agenda). So I don't expect a budget Trump objects to will even make it to his desk. What is likely to happen is that the Senate will use this as a negotiation tool with the house. It -will- lead to a compromise eventually (but with a decent chance of government shutdown first), which will end up funding most of the things Trump wants, AND most of the stuff Dems want, leading to a further increase in the deficit.
