House Speaker Nancy Pelosi (D-CA) received a letter yesterday from reform groups on her leadership involving recent House Lobby and Ethics reform legislation. A similar letter was sent to Senate Majority Leader Harry Reid (D-NV). The letter calls on the Democratic leaders to keep the strong provisions in their respective bills intact so that numerous changes do not weaken the bill during the upcoming conference report. The groups express concern for the bundling provision, maintaining the disclosure by lobbyists of their fund-raising events, and disclosure of lobbyists bundling contributions. Groups that signed the letter include the Campaign Legal Center, Common Cause, Democracy 21, the League of Women Voters, Public Citizen and U.S. PIRG. Meanwhile, the Hill reports on a possible recommendation for changes to the House Ethics enforcement process. A provision of the proposal would require groups to reveal their donors if they file ethics complaints. And now many groups have expressed opposition to the donor disclosure measure.
