WASHINGTON -- A top adviser to President-elect Barack Obama said Tuesday that the transition team would raise about $7 million to cover its costs, supplementing $5 million in government funds, but would reject donations from lobbyists or corporations and rely instead on the same pool of small donors who helped propel the Democrat to victory.

“We’ll raise all that money from individuals,” said John D. Podesta, who is a co-chairman of Mr. Obama’s transition team. “There’s a $5,000 limit on those contributions.”

In his remarks to a packed briefing room in the temporary transition offices here, Mr. Podesta, a former of chief of staff to President Bill Clinton, seemed intent on striking a tone of brisk efficiency and in advertising what he insisted would be historically high standards.

Under the rules announced by Mr. Podesta, federal lobbyists will not be allowed to raise money for the transition, nor continue lobbying while working in the transition. In addition, he said that someone who became a lobbyist after being involved in the transition would be prohibited from lobbying the administration on related matters for 12 months.
