Moveon.org targets Brown in phone campaign to pass Disclose Act

"The Disclose Act, which just passed the House, will force corporations to be more transparent about how much money they're spending in this election cycle," the e-mail states. "Now it's in the Senate where its fate could be decided by one single vote. Scott Brown has said he'll consider voting for the bill after November... Can you call him and tell him we need the Disclose Act now ...?" 

The e-mail provides the telephone number to Brown's congressional office and asks those who call him to report back to the organization details of the chat.   

Today's action by liberal group comes on the heels of a handful of organizations sending a letter to Maine Republican Sens. Olympia Snowe and Susan CollinsSusan Margaret CollinsOvernight Health Care: 3.6M signed up for ObamaCare in first month | Ryan pledges 'entitlement reform' next year | Dems push for more money to fight opioids Study: ObamaCare bills backed by Collins would lower premiums Right scrambles GOP budget strategy MORE urging them to support the bill.

"Your vote on the Disclose Act will be a vote on the most important government integrity reform measure to be considered thus far by the Senate in this Congress," the letter states. "This critical 'transparency' legislation deserves your support. Any effort to filibuster the Disclose Act deserves your opposition." 

The letter was sent by organizations like the League of Women Voters, the Campaign Legal Center, and Democracy 21.

The House passed the legislation 219-206 before adjourning for the July 4 recess. Its narrow victory there has some wondering if it has enough momentum to get through the Senate.
