President Obama is going to Copenhagen.
The president will leave Thursday and will join his wife, Michelle, and others in his administration, in leading the U.S. appeal for the 2016 Summer Olympic Games in Chicago.
The planned trip will make Obama the first U.S. president to take on such a direct role in lobbying for an Olympics event.
The president will be a part of the formal presentation on Friday morning with Mrs. Obama.
White House senior adviser Valerie Jarrett tells ABC News' Ann Compton that both the president and Mrs. Obama will participate in the Q & A session.
He will be back in D.C. by Friday evening.
A White House official says the president decided to go at this late hour because the competition looks very close.
President Obama believes "it's gonna take everything we got" to win, reports ABC's Yunji de Nies.
Two Obama Cabinet members from Illinois -- Education Secretary Arne Duncan and Transportation Secretary Ray LaHood – are also going. Chicago is in competition with Rio de Janeiro, Madrid and Tokyo. Chicago Mayor Richard Daley heralded the news that President Obama would join his wife (and Oprah) in Copenhagen.
"President Obama and First Lady Michelle Obama symbolize the hope, opportunity and inspiration that makes Chicago great, and we are honored to have two of our city's most accomplished residents leading our delegation in Copenhagen," said Daley.
