What action by president Richard Nixon spurred the protests at Kent state

Answer: On April 30, 1970, President Nixon authorized U. S. troops to invade Cambodia, a neutral nation located west of Vietnam. Even before Nixon's formal announcement of the invasion, rumors of the U. S. military incursion into Cambodia resulted in protests at colleges and universities across the country.

Explanation:At Kent State, these protests actually began on May 1, the day after the invasion. That day, hundreds of students gathered on the Commons, a park-like space at the center of campus that had been the site of large demonstrations and other events in the past. Several speakers spoke out against the war in general, and President Nixon specifically.
