Less than a fifth of House members disclosed their earmark requests for the upcoming transportation reauthorization bill, according to the Sunlight Foundation.

Unlike the House Appropriations Committee, the Transportation and Infrastructure Committee doesn't require members to post their earmark requests online before they submit them to the committee for consideration. Sunlight's 'real time investigation' staff did the yeoman's work of scrolling through member's websites searching for transportation earmark requests through yesterday's deadline.

"[Congress has] got to come up with a better way for the public to find this information," said Bill Allison, senior fellow at the Sunlight Foundation. According to Allison, lawmakers submit earmark requests through a web-based form, which would make it easy to create a central database.

Sunlight is rallying support for a new resolution sponsored by Reps. Bill Cassidy, R-La., and Jackie Speier, D-Calif. The resolution would require a more robust online disclosure of earmarks. Read more about the legislation here.
