Earlier in the day, Murphy slammed the policy in a Huffington post op-ed

“Trump has now handed ISIS a path to rebirth,” Murphy said the post. "They can and will use his announcement today as confirmation that America is at war with Muslims, especially those Muslims living in desperate circumstances.

“Their recruitment bulletin boards will light up with new material. Their entreaties to would-be lone wolf attackers in America will have new energy and purpose,” he added.

“All the work we have done to cut down on extremist recruitment at home and abroad now goes out the window. It’s a new day for terrorist recruiters.”

Trump’s order indefinitely bans Syrian refugees from coming to the U.S., and puts a 120-day halt on the refugee program at large. 

It also temporarily suspends U.S. entry from Iran, Iraq, Libya, Somalia, Syria, Sudan and Yemen. All seven nations appear on a handful of government lists designating sponsors of terrorism and "countries of concern."
