Trump says he's "moving on" to other legislation but he is delusional: He heads the Executive Branch, not the Legislative Branch. He doesn't get to write legislation, Congress does.
And Congress can do what ever they want, when they want. Trump can go blow it out his azz. All he really gets to contribute to legislation is to sign or not sign bills when they get to his desk. He can't write anything. (And looking at his joke of a budget, apparently doesn't have the ability to write anything more complex than a campaign slogan.)
Maybe he needs to watch that "How A Bill Becomes A Law" movie again.
