Minden Congressman John Fleming tells 710 KEEL that most mosques in America are run by radical imams.

"There are people who are experts in this area that tell us that as many as 80% of the mosques in America have radical imams, teaching hatred against Americans," Fleming explained.

More details are being unveiled about the reason Dzhokhar and Tamerlan Tsarnaev decided to bomb the Boston Marathon.

"The vast majority of Muslims as far as we know in America they are non-violent, they want to be good citizens."

However, Fleming says it is the small minority within the Muslim community that we need to be concerned about.

"When you have someone who is preaching hatred, not just against the U.S., but Israel and the West in general you've got 1 percent, especially young people who may be open to some suggestions," suggested the Minden congressman.

As details of the Boston Marathon Bombing continues, Dzhokhar Tsarnaev told investigators he and his brother worked alone.

Terror organizations have been using media as a way to radicalize young Muslims.
