The Democratic National Committee has issues the following statement:

“The DNC and the Obama Campaign are unified and working together to elect Barack Obama as the next president of the United States. Our presumptive nominee has pledged not to take donations from Washington lobbyists and from today going forward the DNC makes that pledge as well,” said Democratic National Committee Chairman Howard Dean. “Senator Obama has promised to change the way things are done in Washington and this step is a sure sign of his commitment. The American people’s priorities will set the agenda in an Obama Administration, not the special interests.”

Earlier today George Stephanopoulos broke the story.
