"The men and women of law enforcement, first responders and medical professionals should be commended in their heroic actions to rescue the victims in extreme weather conditions", she said in a statement.
The aircraft took off on Saturday shortly before noon local time from Chamberlain towards Idaho Falls, about 1,000 kilometres to the west.
The area is under a severe winter storm warning with heavy blowing snow or freezing rain. The NTSB will manage the investigation.
An official from the National Transportation Safety Board told NewsCenter1 that the plane was a Pilatus PC-12, a single-engine turboprop aircraft. Local authorities are guarding the wreckage, with federal investigators expected to arrive by Monday. Their conditions have not been released and EastIdahoNews.com is not reporting their names or the names of the other fatalities at this time.
Knudson says weather will be among several factors NTSB investigators will review, but no cause has yet been determined.
All people aboard the plane were from Idaho, Maule Rossow told The Washington Post.
The East Idaho News reported that those killed included Jim Hansen Sr, his sons Kirk and Jim Hnasen Jr., and six other members of their family.
