text: BOSTON, MA - JANUARY 28: Mazdak Tootkaboni is welcomed during a demonstration against the new ban on immigration issued by President Donald Trump at Logan International Airport on January 28, 2017 in Boston, Massachusetts. Tootkaboni is a U.S. green card holder from Iran and a professor at the University of Massachusetts at Dartmouth, but he was still separated from other passengers and questioned as a result of the new immigration ban issued by President Donald Trump. President Trump signed an executive order that halted refugees and residents from predominantly Muslim countries from entering the United States. (Photo by Scott Eisen/Getty Images
