Bloomberg’s Sahil Kapur writes that, even as President Trump prepares to push tax reform thus week, basic questions about the plan have no answers: “Will the changes be permanent or temporary? How will individual tax brackets be set? What rate will corporations and small businesses pay?”

“They’re nowhere. They’re just nowhere,” Henrietta Treyz, a tax analyst with Veda Partners and former Senate tax staffer, tells Kapur. “I see them putting these ideas out as though they’re making progress, but they are the same regurgitated ideas we’ve been talking about for 20 years that have never gotten past the white-paper stage.”
