After an apparent white supremacist carried out a deadly terrorist attack in Christchurch, New Zealand, killing dozens of people attending mosque, only a few Democratic candidates running for president in 2020 specifically called out the problem of white supremacy.

The mass shooting at two New Zealand mosques on Friday left at least 49 people dead and people the world over in mourning.

A suspect in the attack appeared to be a white supremacist﻿ motivated by U.S.-based extremism. The gunman, whose identity has not been confirmed, apparently posted a manifesto online declaring his hatred for Muslims, idolizing U.S. extremist movements, claiming he donated to white supremacist groups and reciting the “14 words,” a white supremacist slogan.

New Zealand Prime Minister Jacinda Ardern described the massacre as a “terrorist attack” at a news conference, saying: “These are people who I would describe as having extremist views that have absolutely no place in New Zealand and in fact have no place in the world.”

Among the crowded Democratic field for 2020, only a handful of candidates called out the issue of white supremacy in so many words in their statements of condolences.

Sen. Cory Booker (D-N.J.) said he was “sickened” by the news of the “horrific terrorist attack.”

“The rising tide of white supremacy and Islamophobia around the globe must be met with our determination to work against hate,” Booker tweeted.
