Senator Chuck Schumer (D-NY) introduced a revised version of the DISCLOSE Act (S. 3628) on July 21, in hopes of gaining some much needed support from moderate Republicans before the upcoming August recess.

The new bill includes changes to address concerns that the bill favored unions. For example, a provision in the House passed version exempted unions from disclosing the transfer of money between affiliates. The revised bill removes this, and also keeps a controversial carve-out for large, 501(c)(4) membership groups. The changes have reportedly created concerns with the AFL-CIO. According to POLITICO, an AFL-CIO spokesman said, "We continue to review the legislation and fight to ensure that the final bill addresses the tilted advantage that big business has enjoyed for far too long."

Another change would only require groups to state their geographic locations in television ad disclaimers and not radio ads because television ads could do so visually.

Senate Majority Leader Reid filed cloture late Thursday night on a motion to proceed to the bill. However, it remains uncertain whether the bill will have the 60 votes needed to overcome a possible Republican filibuster. A vote on whether to proceed with the DISCLOSE Act is expected on Monday, July 26.
