Every original Senate co-sponsor of legislation that would block transparency of federal contractor political contributions can count government contractors as top donors to their campaign, according to Public Campaign analysis of campaign data provided by the Center for Responsive Politics and federal spending data by FedSpending.org.

The bill, S. 1100, is meant to short-circuit possible plans by the Obama administration to sign an executive order that would require government contractors to disclose their political spending. We looked at the top 20 donors to each Senator during their time in Congress and below are the government contractors that fall under those lists.
