Obama to Speak at Organizing for Action Event

Political nonprofit Designed as successor to his electoral campaign

President Barack Obama will speak to a Wednesday night dinner for donors and grass-roots supporters at the "founders' summit "of Organizing for Action, the nonprofit successor organization to his campaign, officials said.

The summit, to be held Wednesday and Thursday at a Washington hotel, is aimed at keeping supporters motivated ahead of tough congressional fights on gun legislation and immigration reform and to take their temperature about the future of the organization.

Speakers will include David Plouffe, former White House senior adviser, and manager of Obama's 2008 campaign; Jim Messina, manager of the 2012 campaign and OFA's national chairman; Jon Carson, OFA's executive director; Dan Wagner, the campaign's chief analytics officer; Lisa Jackson, Obama's former EPA administrator; Sara El-Amine, OFA's national organizing director; Lindsay Siler, OFA's issues director; and others.
