House and Senate GOP leaders forged an agreement Wednesday on a sweeping overhaul of the nation’s tax laws, paving the way for final votes next week to slash taxes for businesses and give many Americans modest tax cuts starting next year. Top GOP aides said lawmakers had reached an agreement in principle on the final package. Details still need to be drafted and assessed by congressional scorekeepers, but the final House-Senate compromise is on track to be unveiled this week, the aides said.
