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.

Some House GOP members have voiced reservations about the bill. House Democrats are united in their opposition to the legislation.
