WATCH: Trump Honors Victims of Saturday Synagogue Shooting During Rally

Speaking at a rally in Green Bay, Wisconsin, on Saturday evening, President Trump paid his respects to the victims of the horrific shooting at a Jewish synagogue in Poway, California, earlier in the day.

The president also honored the off-duty Border Patrol agent who responded to the attack, killing the assailant before he could murder or harm any additional victims.

“Our entire nation mourns the loss of life, prays for the wounded, and stands in solitary with the Jewish community,” said a somber but determined Trump, who vowed that the “evil of anti-Semitism and hate must be defeated.”

“We are grateful to the law enforcement personnel for their courageous response,” said President Trump, who said he “especially wants to recognize a certain off-duty Border Patrol Agent who helped disrupt the attack and saved so many lives.”

The shooter, reported to be a white supremacist, killed at least one victim during his attack, and wounded several others in what is being described as a hate crime by law enforcement.
