Trump: Being in Terrorist Propaganda Shouldn't Stop Us From Speaking About the Enemy

The man accused of supplying weapons to the San Bernardino terrorists pleaded not guilty in court today.

Charges against Enrique Marquez Jr. range from providing material support to terrorists to committing marriage fraud. He faces up to 50 years in prison, if convicted.

But perhaps most remarkable is the amount of incriminating information Marquez himself revealed in a near-fortnight interrogation with federal authorities, said Judge Napolitano on “Shepard Smith Reporting.”

“This guy sang like a bird for 12 days,” he said. “He was charged today on the basis of words that he himself gave against himself.”

“Usually when you do this, you have a lawyer with you, and you get something in return,” said Judge Napolitano. “It doesn’t look like that happened here.”

It is unclear whether Marquez had a lawyer with him when he made his confessions to the FBI.

Marquez fell under national scrutiny after the FBI identified him as the buyer of two rifles used in last December’s attack that killed 14 people.

Though he claims he didn’t know that Syed Farook would use them in the San Bernardino shooting, officials say he did know that Farook had planned to use them in some kind of terrorist attack, Jonathan Hunt reported from Riverside, Calif.
