Records show the U.S. government spent nearly $5 million to court-martial and convict former army psychiatrist Major Nidal Hasan in the 2009 Fort Hood shooting rampage.

The biggest pretrial expense was transportation for witnesses, jurors and attorneys, coming in at more than one million dollars. About $900,000 was spent on their accommodations.

Records also show that the government also spent more than $194,000 in helicopters transportation for Hasan. This was so Hasan could work on his defense in his private office, after being charged.
