Rufus Gifford, who the White House said will be nominated as U.S. ambassador to Denmark, was finance director for the Obama campaign in 2011 and 2012.
John Emerson, the president of Private Client Services for Capital Group Companies, will be nominated as ambassador to Germany. Emerson was a financial bundler - a donor who also collects money from others - for Obama's re-election campaign
James Costos, an HBO vice president who also was a 2012 Obama bundler, will be nominated as ambassador to Spain.
Liliana Ayalde will be tapped for Brazil, Ken Hackett for the Holy See, and Patricia Marie Haslach for Ethiopia, the White House said.
Ayalde, a former ambassador to Paraguay, and Haslach are career State Department diplomats.
