Southbend, Indiana, Mayor Pete Buttigieg told the forum, “America is under attack from homegrown white nationalist terrorism.”

“White nationalism is evil, and it is inspiring people to commit murder, and it is being condoned at the highest levels of the American government … The president of the United States is condoning white nationalism. … We are the only country in the world with more guns than people. It has not made us safer. We can respect the Second Amendment and not allow it to be a death sentence for thousands of Americans.”

Sen. Bernie Sanders (I-Vt.) tweeted Americans must reject the “dangerous and growing culture of bigotry espoused by Trump and his allies.” Instead of “wasting money putting children in cages” the U.S. needed to “address the scourge of violent bigotry and domestic terrorism,” Sanders said.
