WH policy director: From campaign hype-man to Oval Office influence

Stephen Miller, President Donald Trump’s speechwriter, confidante and the author of his controversial immigration ban, has operated on the fringes of his own political party since he was a teenager.

But after what appears to have been a momentous White House policy coming out week, featuring Miller at its center, that’s no longer the case. The California native has brought his views on immigration, multiculturalism and political correctness to the President’s desk.

He’s also helped Trump in his mission to disrupt Washington, ruffling feathers with the secretive way in which he helped lead the White House release of its temporary immigration ban from seven Muslim-majority countries late on Friday with little to no input from the government agencies tasked with implementing the vision.

But rather than a slap-dash effort, which is how the executive action seemed to unfold, Miller actually spent months crafting the order, a White House official said.
