Frustrated by the growing secrecy that shrouds political spending, some good-government advocates have set out to at least pull back the curtain on lobbyists. They’ve found some surprising allies on K Street, where many lobbyists themselves argue that outdated disclosure rules leave a world of lobbying activities unreported. … The lobbyists league has already endorsed eliminating the 20 percent exemption, arguing that all lobbyists should be held to the same standard. … A task force of the American Bar Association is also game to throw out that exemption; in January, it recommended a package of lobbying reforms that the full ABA will consider this summer. The task force set out to define ‘the next generation of lobbying reforms,’ said Thomas M. Susman, who directs the ABA governmental-affairs office. Organized by the ABA’s Administrative Law and Regulatory Practice Section, the task force made some recommendations that make lobbyists look like reform advocates. One proposal to separate lobbying from fundraising would raise some eyebrows on Capitol Hill. In essence, a lobbyist would not be permitted to lobby a member of Congress for whom he or she had raised campaign money in the past two years. It would discourage K Street pros from bundling donations and organizing fundraisers, although direct contributions from individual lobbyists would be permitted.
