(CNN) - The Democratic Senate and congressional campaign committees will not accept cash from political action organizations or lobbyists during a fundraiser to be headlined by President Obama, a Democratic source confirms to CNN.
The White House stipulated the condition for the major June 18 fundraising event, expected to raise millions for 2010 Senate and congressional candidates.
Obama banned PAC and lobbyist donations during the presidential campaign to square with his pledge to limit the influence of special interests in Washington. He instituted a similar rule at the Democratic National Committee after winning the White House.
But both the Democratic Senatorial Campaign Committee and the Democratic Congressional Campaign Committee - which along with their GOP counterparts have historically relied on PAC and lobbyist contributions - will return to accepting such funds after the Obama fundraiser.
