At Minnesota’s northernmost border, about 120 people filled the Warroad Baptist Church to hear former FBI agent John Guandolo warn them about what he calls the threat of Islam.

It was big turnout for an event that was not advertised in a town of less than 2,000 people.

“Are you prepared?” Guandolo called out. “Are you prepared for the two or three dozen jihadis in, pick a city in Minnesota, with mortars or shoulder-fired rockets? You don’t think they can get those in the United States?”

North and central Minnesota have become fertile ground for traveling speakers who have built national careers spreading alarm about the danger they say Islam poses inside U.S. borders.
