Council on American-Islamic Relations office in DC evacuated after foreign substance received in mail

The U.S. Muslim advocacy group, Council on American-Islamic Relations (CAIR), said on Thursday its Capitol Hill office was evacuated by police after a foreign substance was received in the mail.

CAIR's Instagram page showed the Washington office blocked off with yellow police tape and a group of emergency vehicles blocking the street.

The incident came days after Republican presidential candidate Donald Trump issued a call to prevent Muslims from entering the United States until the government could set up better screening for those seeking to enter the country.
