On Monday, Mr. Spicer said that Mr. Trump remained under audit
and that, breaking with 40 years of presidential tradition, his tax returns would not be made public.
The Trump administration’s tax plan, promised in February, has yet to materialize; a House Republican plan has bogged down, taking as much fire from conservatives as liberals; and on Monday, Treasury Secretary Steven Mnuchin told The Financial Times
that the administration’s goal of getting a tax plan signed by August was “not realistic at this point.”
A tax overhaul could be the next expansive Trump campaign promise that falters before it even gathered much steam.
“If they have no plan, they can’t negotiate,” said Larry Kudlow, the economist who helped Mr. Trump devise his campaign tax plan.
Polls show that a majority of Americans, including most Republicans, would like Mr.
Trump to release his tax returns, according to the Republican pollster Frank Luntz.
Trump’s Unreleased Taxes Threaten Yet Another Campaign Promise -

plan, the focus on his tax returns suggests that any legislation will happen along party lines.
