WASHINGTON — Rep. Chris Cannon's cooperation with his lobbyist brother Joe Cannon has earned him attention on a list of "corrupt" members of Congress.

The Citizens for Responsibility and Ethics in Washington named Cannon, a Republican who represents Utah's 3rd Congressional District, as one of five "members to watch" in its second annual report ranking the 20 "most corrupt" members of Congress.

The group, known as CREW, gave Cannon a "dishonorable mention" because of his "abuse of his position to benefit his brother Joseph Cannon, a registered lobbyist."

Chris Cannon has maintained that he treats his brother as he would any other lobbyist.

Joe Cannon is also the chairman of the Utah Republican Party and on the board of directors of the Deseret Morning News.

Joe Cannon told the newspaper Wednesday afternoon that in light of the recent criticisms "I've decided not to lobby my brother anymore. I won't take clients to see him. If they want to talk to him, I'm just telling them to go call him themselves."

According to the CREW report, Joe Cannon has repeatedly sought his brother's assistance on behalf of clients. "Rep. Cannon has a financial interest in his brother's lobbying success because Joseph Cannon owes him more than $250,000 from his unsuccessful 1992 campaign for the U.S. Senate," it said.

Joe Cannon said he only talked to his brother about two issues — issues that any other lobbyist handling those issues would have talked to Rep. Cannon about anyway.

The report said Rep. Cannon, along with three other lawmakers, pushed for a congressional hearing on a proposed contract affecting Internet companies. Joe Cannon is a lobbyist for Network Solutions Inc., which sells Web addresses and opposes a price increase it would pay to another company under the pending agreement. Rep. Cannon signed a letter asking for a congressional hearing on the deal.

Charles Isom, Chris Cannon's spokesman, said the congressman has a long history on Internet issues, and it was not like his brother came to him asking for support on an issue he knew nothing about.

"This is something he is very familiar with, and had anyone come to him with this, he would have signed it," Isom said.

Isom said any notion that Joe Cannon has "undue influence" on the congressman "is wrong."

No federal laws prohibit relatives from lobbying lawmakers, but CREW points to rules that prohibit House members from "taking any official actions for the prospect of personal gain for themselves or anyone else."
