On Monday, President Trump vaguely elaborated on a 10 percent tax cut for middle-income earners that nobody else seems to know anything about. Trump's proposal for a "major tax cut" before the Nov. 6 election or soon after is "mystifying White House officials, congressional leaders, and tax wonks around town who mostly have no idea what he's talking about," Politico reports. At a rally in Houston on Monday evening, Trump said he has been working on the proposal with House Ways and Means Committee Chairman Kevin Brady (R-Texas) for several months, and he's said House Speaker Paul Ryan's office was involved, too.
