FORT HOOD, Texas (AP) President Barack Obama has reacted to the Fort Hood shootings saying he was following the situation closely and that the government will get to the bottom of what happened.

He said Wednesday's incident brought back painful memories of a 2009 mass shooting at the Texas Army post. Thirteen people were killed and more than 30 wounded in what was the deadliest attack on a domestic military installation in history.

"We're heartbroken that something like this might've happened again," Obama said at a restaurant in Chicago where he held a fundraiser.

"The folks there have sacrificed so much on behalf of our freedom. Many of the people there have been on multiple tours to Iraq and Afghanistan," Obama said. "They serve with valor, they serve with distinction and when they're at their home base, they need to feel safe. We don't yet know what happened tonight, but obviously that sense of safety has been broken once again."
