President Obama met today with family members of those killed in the attacks on 9/11 and the USS Cole.
Many of them are angry that Obama has put a halt to the trials of terrorist suspects being held at Guantanamo Bay.
Yesterday a Pentagon judge acted on Obama's order, and dropped charges against an Al-Qaeda suspect in the Cole attack.
Seventeen U.S sailors were killed when terrorists bombed the Cole in 2000.
The victims' families say they've already waited too long to see the terrorists brought to justice.
