Cuba ? The Pentagon will not try to use emergency powers to build a compound to hold war crimes trials at Guantanamo Bay, according to a member of a Senate panel that oversees funding for military construction projects.

The U.S. Defense Department notified Sen. Dianne Feinstein that it canceled a contract solicitation to build the new courthouse complex at the isolated base in southeast Cuba because of concerns about the location and funds for the facility, according to a statement from her office.

The Defense Department recently sent a letter to Congress announcing its intention to fast-track the Guantanamo complex by reallocating $102 million of its authorized funds by invoking its emergency powers to bypass congressional approval, Feinstein said.

A Pentagon spokesman gave no specific details about the cancellation, which was first reported Sunday by The Miami Herald. But he said that due to the scope and complexity of the trials for terror suspects, additional infrastructure and personnel are still needed at Guantanamo.
