Harvard University, America’s oldest and wealthiest institute of higher learning, is at a crossroads as it weathers the Trump administration’s attacks. Outwardly, the university has become a symbol of defiance for refusing to cave to the administration’s demands, but on campus, many say the mood is one of frustration and fear, particularly for international students and faculty.

"Students are unsure whether they can publish, whether they can travel, and wondering whether they can finish their degree,” Jocelyn Viterna, the chair of studies of women, gender and sexuality and a sociology professor at Harvard, said about international students. “I know students are also afraid that they might end up in a Louisiana prison because of something they happen to like once on Facebook.” More at the link in bio. 📷️ @lucyluphoto for @nbcnews
