The Senate on Thursday once again blocked consideration of a controversial campaign finance measure that would require greater disclosure of corporate campaign spending.

A cloture motion to begin debate on the DISCLOSE Act fell short on a 59-39 vote. The outcome likely puts the legislation on the back burner until after the midterm elections, but it is unclear whether Majority Leader Harry Reid (D-Nev.) will try to take the issue up again during a lame-duck session.

The DISCLOSE Act has already passed the House.
