An amendment to the bill which passed the Senate on Tuesday could drastically reduce the ability of gamblers to turn a profit.

The House convened Wednesday to take up President Trump's Senate-passed massive domestic policy bill, with Republicans aiming to approve the final version of the legislation ahead of a July 4 deadline to get the bill to the president's desk.

The legislation now heads to the floor, where members have been told per a whip notice that they could expect votes beginning as early as 9 a.m. on Wednesday.
