The two U.S. senators from Texas, John Cornyn and Ted Cruz, have introduced a bill to declare the 2009 Fort Hood shooting an act of terror instead of "workplace violence."

The definition might not seem important, but it is critical for the victims of the Fort Hood shootings and their families.

Because the shooting took place on U.S. soil, the victims are not receiving the same medical benefits as their fellow soldiers who are injured in a combat zone.

The bill argues that shooter Nidal M. Hasan was motivated by Islamic extremism and proved to be a terrorist, a traitor and an enemy of the United States.

“The wheels of justice have turned too slowly for the victims of the terrorist attack at Fort Hood four years ago," the author of the bill, Cornyn, said in a statement. "We must direct our attention to the people who deserve it, and that is the victims and their families. As a nation, we have a sacred obligation to take care of them.”

At this point, U.S. Sens. Susan Collins, R-Maine, and Jerry Moran, R-Kan., are also co-sponsors along with Cruz.

The bill would require Purple Heart awards to the soldiers killed or wounded in the attack and make the victims of the attack and their families eligible for combat-related compensation and benefits.

Thirteen people were killed and 32 others wounded in the shooting. Hasan received a death sentence from a military court last month.
