Part-time Colorado State sociology professor Steven Helmericks criticized the war in Iraq as pointless, said Heather Schmidt, a 20-year-old Army veteran whose husband was fighting in Iraq at the time.
He also promised to lecture on how "un-great" Ronald Reagan was and drew pointy ears and a dumb expression on a rendering of President Bush.
CSU president Larry Penley said Helmericks was disciplined. Student Meg Ryan, who supports Helmericks, said he taught only two days this fall before being banned from class.
College presidents would not detail the discipline, citing state personnel privacy laws.
The professors were not present to defend themselves during the hearing, and attempts to reach them Thursday were unsuccessful.
The new accusations come on top of allegations that emerged in two previous legislative hearings.
Meranto and Helmericks said they received death threats following publicity over the incidents and reported them to police, according to testimony.
Ryan said she took Helmericks' class on the recommendation of other students this fall and was told by other students that the incident was "exaggerated and taken out of context. This professor has been silenced because of the complaint of one student."
"The allegations seemed to have some credibility; however, it's hard to be sure whether or not a problem really exists because we were given testimony by three or four students, and we have tens of thousands of students," said Sen. Ron Tupa, D-Boulder, who likened the hearing to a witch hunt.
"I don't see a pattern, I don't see a trend, and frankly I'm not sure I see a problem. You may have a few bad apples among the otherwise thousands of fine dedicated faculty."
Students with differing views on either the professors or the ideological debate said they were told Wednesday they would not be allowed to testify.
Andrews disputed that, saying, "Our announcement made clear that public comment would be received."
Thursday's hearing stemmed from a memorandum of understanding signed this year by college presidents who promised to update lawmakers periodically on their progress in protecting students from political discrimination and indoctrination.
The issue rose to the forefront a year ago after Andrews and other Republicans met with David Horowitz, a Los Angeles conservative pushing for an "Academic Bill of Rights" for students.
The policy has professors afraid of crossing the line as they discuss political science, evolution or stem-cell research, college presidents and professors said.
"It has had a chilling effect," Kieft said. "Faculty members are much more conscious about the topics they address and what they say because they're not sure what's acceptable."
CU evolutionary-biology professor Michael Grant says he worries about the policy. "I'm careful to always say that we are going to stay strictly in the scientific arena, and some students are angry and think it unfair that we don't include their views."
CU student Josh McNair complained Thursday that the nondiscrimination policy espoused by lawmakers is only invoked when convenient. McNair said his attempts to bring Holocaust revisionist David Irving to campus were denied.
