The attorney for Army Sgt. Bowe Bergdahl said Monday he hasn't been updated on an investigation that could lead to a court-martial for his client, who left his post in Afghanistan and later was held by the Taliban for five years.

"We are completely in a holding pattern," Yale Law School lecturer Eugene Fidell said. "I feel like the Maytag repairman. I'm just waiting for the phone to ring."

The Army said it had nothing new to report on the inquiry led by Brig. Gen. Kenneth Dahl. Fidell said his client's enlistment term had ended and he wanted to leave the Army.

Dahl's report will be a key to Bergdahl's future. Dahl questioned Bergdahl last month in San Antonio about his decision in June 2009 to leave his combat post in Afghanistan.

Bergdahl was captured and held for five years by the Taliban until he was released in May in a controversial prisoner swap.

He was the longest-held American POW in the war.

He has been at Fort Sam Houston-San Antonio since June 13.

Some fellow soldiers recalled him talking about walking off the base, and others said GIs died in a futile search for Bergdahl, but the Army said it could not substantiate those claims.

A House panel in late July voted mostly along party lines to condemn the prisoner swap. The full House will take up the resolution as early as this week.

The nonpartisan Government Accountability Office last month said the Defense Department failed to notify the relevant congressional committees at least 30 days in advance of the exchange, a clear violation of law.

It said the department's use of $988,400 in funds that hadn't been expressly appropriated violated the Antideficiency Act.

The Army won't say when Dahl will finish his investigation.

His report will go to Lt. Gen. William Grisoli, director of the Army's staff, but a spokesman, Wayne Hall, wasn't clear about what happens next, saying, "It is too premature to determine what actions will occur beyond that point."

Typically, the senior leader in a soldier's chain of command decides how to proceed in a serious disciplinary matter. That means Lt. Gen. Perry Wiggins, commander of U.S. Army North, would decide if a court-martial is required or a lesser form of punishment.

Bergdahl, 28, of Hailey, Idaho, has been assigned to general administrative duties at Army North's headquarters at Fort Sam Houston.

Fidell, one of the nation's best-known specialists in military law, wouldn't discuss Berg-dahl's activities here but said his client wants to focus on his education once out of the Army.

"His time is up. His enlistment has long since expired. He wants to go to college," Fidell said, adding that Bergdahl hasn't decided what to study or where he'll call home. "There are many bridges that have to be crossed before he has to make a decision on where he's going to live."
