Hasan's lead attorney, John Galligan, says he'll urge Campbell not to seek the death penalty because such cases are more costly, time-consuming and restrictive.
If Campbell decides Hasan will go to trial but military jurors cannot consider the death penalty if he's convicted, then the punishment will be life in prison without parole.
Hasan is charged with 13 counts of premeditated murder and 32 counts of attempted premeditated murder in the November 2009 shootings.
