President Obama gave a briefing to press at the White House this morning in which he said that it is not yet known if a group or individual is behind the attacks on the Boston Marathon.
Said Obama: "This was a heinous and cowardly act, and, given what we now know about what took place, the FBI is investigating it as an act of terrorism…We will find whoever harmed our citizens, and we will bring them to justice. We also know this: the American people refuse to be terrorized. Because what we saw in the aftermath of the explosions were stories of heroism and kindness and generosity and love."
Watch, AFTER THE JUMP…
