The Assistant to the President for Homeland Security and Counterterrorism, Lisa Monaco, met at the White House this afternoon with New York City Mayor Bill De Blasio and New York City Police Commissioner William Bratton to discuss strengthening federal, state, and local coordination on counterterrorism issues as well as the U.S. government’s response to the Ebola epidemic in West Africa. On counterterrorism, they reviewed threat streams overseas associated with al-Qa’ida in the Arabian Peninsula, the Islamic State of Iraq and the Levant, and the Khorasan Group, and discussed measures to take to better protect the U.S. homeland from potential threats posed by these groups as well as homegrown violent extremists. They specifically noted the threat from foreign fighters, including Western passport-holders, and the comprehensive, whole-of-government strategy to counter it. On Ebola, they reviewed the status of additional airport screening measures that were implemented at New York’s John F. Kennedy Airport on Saturday and that will be rolled out later this week at Newark and other domestic airports. They also reviewed ongoing efforts to prepare hospitals and healthcare workers nationwide, including in New York City, to identify and treat Ebola patients safely and effectively.
