The action by Senate Republicans to block consideration of the DISCLOSE Act marked a setback for accountability, Congresswoman Kaptur said.
The DISCLOSE Act would require the organizations that are flooding the airwaves with political commercials to reveal their funding sources.
"Senate Republicans voted for secrecy over transparency," said Congresswoman Kaptur.
"Killing the DISCLOSE Act might make the big banks and the oil companies happy, but once again the American people are left in the dark. Those big interests should not outweigh the American people's voices or their votes. The American people should have the primary access and influence here, not deep-pocketed special interests.
"Campaign spending is out of control. Now, to make matters even worse, there is even more secrecy. We need more transparency in the campaign finance system, not less."
