In a Capitol Hill briefing on Monday, Rep. Allen West said it's important to learn just how much progress the Muslim Brotherhood has made in the U.S.
The Brotherhood is considered the grandfather of all Islamic extremist groups and is linked to terrorist organizations.
West, R-Fla., is examining the Muslim Brotherhood's influence in America.
"This is about the protection of each and every American citizen -- whoever resides within our borders," he said.
"It is the initial work product of a 14-month research by the non-profit Citizens for National Security, an all volunteer group that traced the infiltration of the Muslim Brotherhood into America since it came here in 1962," he said.
On CBN News "Newswatch" Monday, Terrorism Analyst Erick Stakelbeck said several major American Muslim groups affiliated with the Muslim Brotherhood have influence with the White House.
"One of the chief groups is the Islamic Society of North America, or ISNA. This is one of the largest American Muslim groups," Stakelbeck said.
"They've been at the White House on a frequent basis," he continued. "They've met with Janet Napolitano, Homeland Security chief."
"These groups, which again I can't stress enough, are named in the Muslim Brotherhood's own documents as friends of the Brotherhood are advising this White House. They also advised the Bush White House on Muslim outreach policy," Stakelbeck added.
The Brotherhood's critics say that while the organization does not practice terrorism, the group is a long-term threat to America's security.
