John McCain's campaign is asking staff members to disclose all previous lobbying ties following the resignation of two officials linked to a firm that worked for Myanmar's military junta.

A memo from McCain's campaign manager, Rick Davis, also instructs staff to make certain they are no longer registered as lobbyists or foreign agents.

It was issued following the resignations of Doug Goodyear, who was to run the Republican National Convention, and Doug Davenport, a regional campaign director for the mid-Atlantic states. Both worked for DCI Group, a consulting firm hired to improve the image of Myanmar's military junta.

"I found out that two people had, some years ago, been involved with the government of Burma, so I needed to fix the problem, and we needed to fix it policy-wise," McCain told reporters Friday on his campaign bus.

Past lobbying work does not automatically disqualify someone from working for the campaign. Davis and another senior adviser to McCain, Charlie Black, were longtime lobbyists but now have severed their lobbying ties.

Like Goodyear and Davenport, Black and Davis have lobbied for foreign governments. And the campaign has other staffers and advisers who are registered lobbyists.

Advisers include former Texas Rep. Tom Loeffler, who lobbies for the European Aeronautic Defence and Space Co., or EADS, which with Northrop Grumman Corp. won a lucrative contract to provide air refueling tankers for the Air Force. McCain helped scuttle an earlier contract that would have gone to a different aircraft manufacturer, Boeing Co.

A staffer, Susan Nelson, also lobbied for EADS. Campaign spokeswoman Jill Hazelbaker refused to comment on any individual aides but said they must sever their ties or leave the campaign. Advisers or other part-time volunteers must disclose their ties and, if they have lobbied, stay away from campaign policymaking, under the new policy.

On Thursday, when the policy was announced, McCain fired an energy policy adviser, Eric Burgeson, who represents energy companies as a lobbyist.

The campaign also asked Craig Shirley to step down as a member of McCain's Virginia leadership team because he was behind an independent group that has been criticizing Hillary Rodham Clinton and Barack Obama on the Internet. That is because McCain's new policy states that no one with a campaign title or position may participate in so-called 527 groups, which can raise unlimited amounts of money for television ads not controlled by campaigns.

Aides would not say Friday if the memo prompted any other departures from the campaign. Continued...
