President Donald Trump said businesses and individuals will receive a “massive tax cut” under a tax reform package he plans to unveil next week — but he’s keeping the details secret until then.

In an interview with The Associated Press, Trump said the plan would result in tax cuts for both individuals and businesses.

But he would not provide details, saying only that the tax cuts will be “bigger I believe than any tax cut ever.”

The president said the package will be released on “Wednesday or shortly thereafter” — just before his 100-day mark in office.

Treasury Secretary Steven Mnuchin initially set a goal of getting tax reform passed by August, but that deadline has slipped.

Mnuchin now says the administration still hoped to get a bill passed well before the end of the year.
