GAO released a new report recently, “2009 Lobbying Disclosure, Observations on Lobbyists’ Compliance with Disclosure Requirements.” The 41-page PDF is available here.
In response to an earlier GAO recommendation, the [U.S. Attorney’s] Office developed a system to help monitor and track enforcement efforts. The Office continues to refine the system to meet the requirements conveyed in GAO’s recommendation. To enforce compliance, the Office primarily focuses on sending letters to lobbyists who potentially violated the LDA by not filing disclosure reports. No civil actions or settlements with lobbyists have been pursued by the Office since 2005, although it is following up on hundreds of referrals each year.
