The Massachusetts Senate has postponed debating a bill requiring political action committees reveal donors in a timely manner.
The Senate was scheduled to debate the bill Tuesday, but will take up the legislation Wednesday.
A version of the bill approved last month by House lawmakers would require so-called super PACs disclose their contributors within seven days of running an ad.
The Senate version would also require disclosure of contributors within seven days.
Both bills would also double the amount an individual could donate to a candidate in a calendar year from $500 to $1,000. The $500 limit was put in place 20 years ago.
The bill would also strike out the $12,500 aggregate campaign contribution limit
A 2010 Supreme Court ruling allowed outside groups like super PACs and nonprofits to take unlimited contributions.
