Forty-five public interest groups have opposed the Democratic bill, which demands more transparency in campaign financing. The news also came that house democrats have convinced the National Rifle Association to leave its opposition to the bill, along with the gun lobbying group.
"There is no legitimate justification for privileging the speech of one entity over another, or of reducing the burdens of compliance for the biggest organization yet retaining them for the smallest”, the group has written in the letter.
The Alliance for Justice, Citizens for Responsibility and Ethics in Washington and, League of Conservation Voters are among the signers of the letter.
Earlier this year, the U.S. Supreme Court had permitted the unlimited contribution to the campaign by corporations, unions and other groups. The bill, if passed by house, will come into effect before the November Congressional elections.
Supporters of this bill were expecting to pass the bill in this week only, but now the assurance of necessary support required in the house is unclear.
Some other public Interest groups have supported the bill; the name of the bill in consideration is The Disclose Act.
According to Doug Thornell, a Van Hollen spokesman, the act would lead to more transparency in the system and citizens would be able to know the senders of money in the elections.
