The court martial of Nidal Hasan earlier this year cost the federal government almost $5 million.
Dallas TV station KXAS-TV tallied the expense from Army records.
All totaled, transporting witnesses, jurors and attorneys for the Fort Hood shooting trial cost more than a $1 million.
Another $90,000 was spent on hotel rooms. Hasan was not allowed to plead guilty to the charges ahead of trial because the crimes carried with them the death penalty.
Hasan acted as his own attorney, asked few questions and called no witnesses to his defense.
A jury convicted and sentenced Hasan to death in August.
The Fort Hood shooting massacre in November 2009 killed 13 and wounded dozens more.
