Morten Wetland said today that the ambassador, Wegger Stroemmen, was approached by Rahm Emanuel, now Chicago's mayor, who accused Norway of "fawning" to the newly elected US leader.
Wetland, the Norwegian ambassador to the United Nations at the time, told The Associated Press he did not witness the dressing down but said there was an air of embarrassment in Washington that Obama had been given the award so early in his presidency.
"It was weird because the UN is a talking shop. And people just looked at their shoes. People didn't raise it with me."
The decision to award the prize to Obama by the five-member committee, which is appointed by the Norwegian Parliament, was met with considerable derision and criticism.

The panel cited Obama's efforts for a world free of nuclear weapons; for a more engaged US role in combating global warming; for his support of the UN and multilateral diplomacy; and for broadly capturing the attention of the world and giving its people "hope."
"To be honest, I do not feel that I deserve to be in the company of so many of the transformative figures who have been honored by this prize," Obama said when he heard the news.
Wetland would not reveal how he knew about Emanuel's meeting with Stroemmen but said Emanuel was known for having a sharp tongue and it was "the job of ambassadors to be available for those lashings out." He declined to elaborate.
Emanuel is now mayor of Chicago.
