Did House Homeland Security chair shake down credit card issuers? Ethics investigates

At a hearing in late March, the nation's credit card companies faced the threat of expensive new rules from an unlikely regulator: the House Committee on Homeland Security, chaired by Rep. Bennie Thompson (D-Miss.).

The committee had never before dealt with credit card issues, but Thompson warned Visa, MasterCard and others that Congress might need to impose tighter security standards costing millions of dollars to protect customers from identity theft.

Behind the scenes, some of Thompson's staffers sensed a different motive -- an attempt to pressure the companies into making political donations to the chairman, according to several former committee staffers.

Now the House ethics committee is investigating the propriety of the committee's operations, and whether its members' interactions with companies compromised its work. Within a few weeks of the hearing, Thompson collected $15,000 in donations from the credit card industry and its Washington-based lobbyists, a Washington Post analysis shows. No legislation on card security has been introduced.

Several former committee staffers, speaking on the condition of anonymity, have told The Post that the credit card hearing was one of several committee actions that caused staff concerns because of their consideration of potential donors and contractors friendly to Thompson. The current ethics inquiry was prompted this summer, according to an ethics document obtained by The Post, when a former committee aide alleged she was fired after complaining to her bosses that a lobbyist made improper requests of staff members.
