FORT HOOD, TEXAS -President Barack Obama says the nation is drawing strength from relatives of the victims of the fatal shootings last week at Fort Hood.
He says the tragedy tears at wounds that are still raw from a deadly mass shooting on the sprawling Army post five years ago.
Obama told relatives of the victims that he's there to honor their loved ones and offer whatever comfort he can.
Officials say Spc. Ivan Lopez fatally shot three soldiers and wounded 16 others before killing himself a week ago at the Texas military base.
Among the injured was Major Patrick Miller, an Allegany County native. He is being hailed a hero for helping others to safety and dialing 911 even after he was shot in the abdomen.
On Monday, Major Miller's father told 2 On Your Side his son is still recovering the hospital. He doesn't know when he will be released.
More than 2,000 people are expected to attend Wednesday's ceremony which is scheduled to begin at 2 p.m. (3 p.m. ET).
The President will help lead today's memorial service just as he did in 2009 following a terrorist attack in which Army Major Nadal Hassan killed 13 fellow soldiers.
