A Republican congressman from North Carolina has joined an effort by House Democrats to bring up legislation requiring corporations and unions to file a Federal Elections Commission report for large campaign spending.

On Tuesday, Rep. Walter Jones (R-N.C.) signed a motion to discharge the legislation, the Disclose Act, out of the on House Administration and the Judiciary committees. The bill challenges the Supreme Court's controversial Citizens United ruling by requiring unions and companies to file an FEC report for donations of $10,000 or more.

Jones is the first and only Republican of the 167 signers on the motion so far. 

To force a vote, Democrats need 218 signatures.

Although Democrats broadly support the legislation, it's unlikely that advocates will be able to get the 218 signatures needed to bring the bill up for a vote.

The Democrat-controlled Senate failed to advance the legislation for a second time a week earlier, in a vote of 53-45.

"It is obvious Republicans’ priority is to protect a handful of anonymous billionaires — billionaires willing to contribute hundreds of millions of dollars to change the outcome of a close presidential contest," Senate Majority Leader Harry Reid (D-Nev.) said after the Senate version of the bill failed.
