House rules forbid members to accept travel expenses from lobbyists, and require that members inquire into the sources of funds that nonprofits use to pay for trips. DeLay denied knowing that lobbyists had paid for travel expenses. In July 2000, DeLay voted against a bill that would have restricted Internet gambling. Both eLottery and the Choctaws opposed the bill. Rudy, who was then DeLay's deputy chief of staff, doomed the bill by engineering a parliamentary maneuver that required a two-thirds majority vote, rather than a simple majority, for the bill to pass. Rudy's actions on behalf of Abramoff's clients during this time were mentioned in Abramoff's guilty plea in January 2006.
