On Thursday, the presidents of 48 American colleges and universities delivered a searing letter to President Donald Trump taking aim at his executive order on immigration.
The letter, drafted by Princeton's president, Christopher L. Eisgruber, and the University of Pennsylvania's president, Amy Gutmann, and signed by 40 other college presidents said:
"This action unfairly targets seven predominantly Muslim countries in a manner inconsistent with America's best principles and greatest traditions. We welcome outstanding Muslim students and scholars from the United States and abroad, including the many who come from the seven affected countries ... This executive order is dimming the lamp of liberty and staining the country's reputation. We respectfully urge you to rectify the damage done by this order."
Their words come amid backlash over an executive order signed by Trump, who cited security concerns, that bars citizens of Iran, Iraq, Libya, Somalia, Sudan, Syria, and Yemen from entering the US for 90 days and bars all refugee immigration to the US for 120 days.
"It really is a statement that felt very personal for me and also a statement about values that I think are defining for Princeton and other universities," Eisgruber told Business Insider.
Eisgruber noted that the order directly affected more than 50 students and faculty members at Princeton. Some of those people are overseas and having difficulty returning to the US, he said, with the rest residing in the US and worried they will be unable to travel internationally to visit family.
Eisgruber, the son of immigrant parents, also spoke about how his family history made the issue personal to him.
"My mother's family fled first from Germany and then from France — they were Jewish and they fled when the Nazis came to power — and they made it to this country in May of 1940," he said. "If we had a refugee ban in place in May of 1940 and my mother and her family had been turned away, they almost certainly would have been murdered."
His father, too, came to the US as an immigrant, as an exchange student from Germany in 1950.
"When I look at these families that are being affected by this order I see my parents and I see the dreams and aspirations that they had the threats that they faced," he said.
