House Republicans promoted their party's proposed tax overhaul on Tuesday as GOP negotiators look to strike a deal on a final bill.

House and Senate lawmakers are working to reconcile the separate tax plans they approved. The chambers hope to pass a joint tax bill before Christmas.

House Speaker Paul Ryan again promoted the GOP tax-cut plan as a method to promote business investment, job creation and wage growth. He also said he believed a Treasury Department analysis that the tax plan would pay for itself, assuming that separate policy changes also happen.

The one-page Treasury report had more optimistic projections about the plan's effect on growth than a congressional analysis or multiple analyses from outside groups.
