Trump tax plan prompts GOP fears about deficit

“We’ll see the score,” said Sen. Ron Johnson (R-Wis.), a member of the Senate Budget Committee.

The Committee for a Responsible Federal Budget, a group headed by Maya MacGuineas, a prominent advocate for deficit reduction, on Wednesday estimated that Trump’s tax plan would cost between $3 trillion and $7 trillion over 10 years, using a traditional cost-scoring method.

Republicans are divided over whether the plan should be deficit-neutral.

Those who argue for deficit neutrality say this would make the cuts permanent while allowing for the use of budget rules that would prevent Democrats from using the filibuster.

Others argue it’s more important to spur the economy through massive tax cuts that they say could lead to economic growth above 4 percent.
