The team defending Fort Carson soldier, Chief Warrant Officer Lewis Welshofer, Junior, asked for a mistrial Wednesday.
Welshofer is charged with murder, in the death of an Iraqi general.
At the court martial a witness said he remembered Welshofer telling him he was involved in the death, and had been told by an attorney not to talk about it.
The judge didn't immediately issue a decision.
