Trump’s violation of 11030 goes way beyond improper margins, however. Section 2 begins, “A proposed Executive order or proclamation shall first be submitted … to the Director of the Office of Management and Budget,” which is part of the White House. If the director of the OMB approves the executive order, it goes to the Justice Department and then to the president.
But there’s no sign Trump’s immigration executive order was routed through the OMB at the start, and lots of evidence it wasn’t.
