The blueprint conflicts with a Senate budget resolution, which doesn't address taxes or the debt ceiling. It also includes less funding than the Senate's for immigration enforcement.

The initial plan calls for $4.5 trillion in tax cuts and at least $1.5 trillion in spending reductions, along with an increase in the debt limit and funds for immigration enforcement.

That plan released Wednesday—headed for a Budget Committee vote Thursday—calls for a minimum of $1.5 trillion in spending cuts over a decade and a maximum of $4.5 trillion in tax cuts from the Ways and Means Committee.
