Lobbyist Disclosure Enhancement Act - Requires the Attorney General to establish the Lobbying Disclosure Act Enforcement Task Force. Grants such Task Force primary responsibility for investigating and prosecuting each case referred to the Attorney General under the Lobbying Disclosure Act of 1995. Requires such Task Force to: (1) collect and disseminate information on the enforcement of such Act; (2) audit at least annually the extent of compliance with such Act; and (3) establish, publicize, and operate a toll-free telephone hotline for members of the public to report noncompliance with lobbyist disclosure requirements.
Amends the Lobbying Disclosure Act of 1995 to: (1) require notifications of noncompliance of lobbyist diclosure requirements to the Attorney General (instead of the U.S. Attorney for the District of Columbia); (2) amend the definition of "lobbyist" under such Act to eliminate the exemption from such Act of certain lobbyists who work for a client on a part-time basis; (3) require lobbyists to register with the Senate and House of Representatives within 5 days after a lobbying contact (currently, 45 days); and (4) expand disclosure requirements relating to contacts with executive and legislative branch officials and political contributions.
