Dershowitz said that because students at most universities are already on break, it is a difficult time of year to organize rallies. He said that at some point, he hoped to see larger protests modeled on the Harvard rally.

We're going to try to put together a major national event based on last night, of scholars and academics across the country, to demonstrate that this is a cultural war between thinking people and fundamentalists," Dershowitz said.

Blinder agreed that more organized protests are necessary to win over a House that appears to favor impeaching the president.

"What we need is thousands of these [rallies] across the country, people letting our representatives know what we think," Blinder said.

Other luminaries who have spoken out against impeachment at campus rallies include feminist Gloria Steinem, actor Alec Baldwin, former Attorney General Nicholas Katzenbach and Nobel Peace Prize winner Elie Wiesel.
