Law enforcement and a hazmat team are on the scene at the Council on American-Islamic Relations (CAIR) headquarters in Washington, D.C., which has been partially evacuated on Thursday due to a suspicious piece of mail.
CAIR, whose mission is to "enhance understanding of Islam, encourage dialogue, protect civil liberties, empower American Muslims," said on social media that its Capitol Hill office was evacuated by police after a powdery "foreign substance" was found in an envelope.
