RAPID CITY, S.D. (AP) - Tribal representatives walked out of a meeting with U.S. State Department officials who came to Rapid City to discuss concerns about the Keystone XL pipeline project.

The Rapid City Journal reports that Oglala Sioux Tribe President Bryan Brewer made a statement dismissing the gathering as a sham because no leadership of the United States was present.

The tribes are concerned about the project's potential impact on sites sacred to the tribes.

A news release says members of the Lakota, Ponca, and Pawnee tribes consider the meeting a "sham" because the Obama administration sent "low level clerks" to meet with tribal and treaty leaders.
