On a conference call organized through Organizing For America, the president lays down the marker on health care reform. Per the Associated Press:

Obama on Thursday told his re-election campaign-in-waiting that volunteers must pressure lawmakers to support the White House's goal on health care -- or else the opportunity would be forever lost. He says delay is unacceptable.

Obama's political organization, Organizing for America, plans a nationwide June 6 kickoff to pressure lawmakers and demonstrate support.
