Just ahead of Tuesday night’s Republican presidential debate in Las Vegas, the nation’s largest Muslim civil rights advocacy organization is calling on all candidates to use the event as an opportunity to speak out against the wave of anti-Muslim and bigoted behavior that has been documented across the nation in recent weeks.

In a statement, the Council on American-Islamic Relations (CAIR) attributed the recent and “unprecedented” spike in hate crimes at least in part to anti-Muslim rhetoric espoused by GOP presidential candidates like Donald Trump, who last week called for a complete ban on Muslims entering America. The group also cited Ben Carson, who earlier claimed that followers of the Islamic faith should never be allowed to be president. Though some rivals of Trump and Carson spoke out against those specific comments, none have gone out of their way to broadly—and unequivocally—condemn the pattern of attacks directed at mosques and individuals who are, or are perceived as being, Muslim.
