The Department of Homeland Security has revealed that federal authorities have opened investigations into radical Islamic terrorists in all 50 states, warning that the threat of terrorism has reached an all-time high.

The FBI has “open investigations in all 50 states,” and there have been at least 37 “ISIS-linked plots to attack our country” since 2013, said DHS Secretary John Kelly on Tuesday.

The U.S. border remains open and the jihadists are working to exploit that national security weakness and plot attacks “every single day,” Kelly said at a George Washington University address.

“We don’t know their intentions,” he said. “We don’t know why they’re here or why they’re coming. We are completely blind to what they’re capable of.”

In the past year alone, there have been “36 homegrown terrorists in 18 states.”

“We’ve seen an unprecedented spike in homegrown terrorism,” Kelly pointed out. “These are the cases we know about – homegrown terrorism is notoriously difficult to predict and control.”

“I tell you, without exaggeration, they try to carry out this mission each and every single day and no one can tell you how to stop it. No one,” he added. “They’re relentless.”

If that isn’t enough, Kelly estimates that approximately 10,000 European citizens have joined the caliphate in Syria and Iraq, and thousands more from Africa and Asia.

“They have learned how to make IEDs, employ drones to drop ordinance, and acquired experience on the battlefield that by all reports they are bringing back home,” Kelly said.

The Trump administration’s DHS policies and rhetoric toward domestic terrorism stands in stark contrast to Obama’s DHS.

Last December, Obama gave a speech to the military boasting that there were zero instances of domestic terrorist attacks, while ignoring the eleven homegrown terrorist attacks including the Boston Marathon bombers and the Fort Hood shooter.

And in 2014, Judicial Watch revealed that Obama’s DHS gave more than 1,500 suspected terrorists asylum in the U.S., claiming any crimes committed were done so “under duress.”
