After a nail-biter vote in the Senate, the House took up President Donald Trump's tax and immigration megabill with a vote possible as early as Wednesday.

The Senate version would have a more substantial impact on the U.S. deficit, according to the CBO. It would add $3.3 trillion to the nation’s debt over a decade, compared with the House bill, which would add $2.4 trillion, the nonpartisan budget scorekeeper found before the final changes were made to the Senate bill.
