PORTLAND, Ore. — An Oregon man charged with murdering two people who had tried to intercede during the man’s anti-Muslim tirade spoke out at an arraignment on Tuesday, calling for “death to the enemies of America” while apparently defending his actions as a form of “patriotism.”

The man, Jeremy Joseph Christian, 35, of North Portland, Ore., is accused of fatally stabbing two men and injuring a third on Friday evening while inside a train car on Portland’s light-rail system.

On Tuesday, Mr. Christian appeared in court here at the Multnomah County Justice Center and was arraigned on nine charges, including two counts of aggravated murder.

As soon as he stepped into the courtroom, he launched into a rant.

“Free speech or die, Portland,” he shouted. “You got no safe place. This is America, get out if you don’t like free speech.”
