WASHINGTON  President-elect Barack Obama has imposed stricter conflict-of-interest restrictions on his White House transition team than any president before him. But a list of transition team members that his office made public on Friday includes a complicated tangle of ties to private influence-seekers.

Among the full roster of about 150 staff members being assigned to government agencies between now and Inauguration Day are dozens of former lobbyists and some who were registered as recently as this year. Many more are executives and partners at firms that pay lobbyists, and former government officials who work as consultants or advisers to those seeking influence.

After campaigning on promises to end the influence of lobbyists in the White House, Mr. Obama has imposed rules that bar officials on his transition team from handling any issues in areas of policy where they have lobbied over the last 12 months or from seeking to influence the same agencies for the next 12 months.

The rules also bar officials from working on matters where family members or recent business associates may have a direct conflict of interest. In cases where there is even an “appearance of conflict,” officials must seek a waiver from the transition’s executive director, an Obama Senate aide and law school classmate, Christopher Lu.
