Sen. Lindsey Graham (R-S.C.) on Friday urged the Obama administration to consider holding the man allegedly behind the bombings of the Boston Marathon as an enemy combatant to help gather intelligence.

Dzhokhar Tsarnaev remains on the run, but Graham, in a series of tweets, suggested that if he is caught alive, he might be a source of information about overseas terrorist groups. He suggested regarding him as a regular criminal and giving him Miranda rights might prove less fruitful.

The United States technically stopped using the term "enemy combatant" in 2009. But it is still understood to refer to a member of the military in a country that is at war with the United States.
