I'm calling on the head of United States Department of Homeland Security General Kelly to rescind Donald Trump's Muslim ban. The Muslim ban will not reduce the threat of terrorism. It is a recruitment gift for ISIS. It's already harming people in Massachusetts as students, professors & others affiliated with hospitals & schools are being separated. We need to know that DHS Secretary Kelly will stand up to President Trump's un-American Muslim ban and other efforts. #NoBanNoWall http://www.markey.senate.gov/…/senator-markey-calls-on-dhs-…
