Today, a U.S. House committee is scheduled to hold a hearing that explores the extent of radicalization in the Muslim community.

Some committee members including Republican Congressman Joe Walsh of Illinois’ 8th district say radical Islam is a threat that must be investigated.

“There are people in this country that want to kill us. They’re being trained to kill us. Don’t we go after that threat? It’s this fear of political correctness that too often gets in the way,” Walsh said.

Democratic Congressman Danny Davis of Illinois’ 7th district also sits on the committee. He says the hearing could do more harm than good.

“We will find ourselves if we’re not careful back in the McCarthy era or something similar to. And people will be denied their individual freedoms, people will be singled out,” Davis said.

Davis says the committee’s time could be better used on other issues, but he says he will participate in the hearing.

Committee Chair Republican Congressman Peter King says Muslims shouldn’t feel threatened by the hearings he is holding. He says it would be “politically correct” to focus on other types of extremism, but that would “water down” the hearings at a time when al Qaida represents what he calls “the main threat to the United States today.
