American universities need to reveal “the malign influence of foreign propaganda” on campus, according to a trio of Republican lawmakers.

Sen. Marco Rubio, R-Fla., introduced legislation Wednesday that would require U.S. colleges and universities to disclose any foreign government donation of $50,000 or more, in addition to requiring foreign-run programs to register as foreign agents with the Justice Department. The bill was spurred by concerns about Chinese-backed entities known as Confucius Institutes operating on dozens of American campuses, but it applies broadly to all foreign governments.
