Republican Presidential Candidate Mitt Romney tried to do a moment of silence in tribute to the four American's killed in the Libyan embassy attack, but it didn't go as planned.

On the anniversary of one of our nations most tragic events, more tragedy struck this week. Four American's, including the US Ambassador, were killed in an attack by Muslims on a Libyan embassy.

Mitt Romney tried to pay tribute to those who had fallen, but a few of his supporters were a bit too rowdy. He lost control of the crowd for the moment of silence and instead got a very empowered 'USA, USA, USA' chant.
