President Trump on Tuesday said that Republicans’ forthcoming tax plan will include “nearly doubling” the standard deduction and increasing the child tax credit.

“We will cut taxes tremendously for the middle class. Not just a little bit but tremendously,” Trump said at a meeting in the White House with a bipartisan group of members on the House Ways and Means Committee.

The president’s comments come one day before the White House and top congressional Republicans release a tax-overhaul framework that is intended to serve as a guideline for the Ways and Means Committee and the Senate Finance Committee as they craft legislation. Trump is also planning to sell the plan during a speech Wednesday in Indiana.

Trump said that the framework would be “comprehensive” and a “very, very powerful document.”
