A pro-Israel student activist at San Francisco State University was escorted off the campus on Monday by police officers and forbidden to return for two weeks following a heated argument with a student-discipline officer.

Natalia Menaker, a Russian immigrant majoring in English, was on disciplinary probation and had received numerous warnings because of her often disruptive methods of voicing her Zionist views. She had repeatedly threatened administrators, students, and faculty members, according to Christina Holmes, a university spokeswoman.

During a meeting to discuss Ms. Menaker's probation violations, Ms. Holmes said, the student was warned that the police would be called if she did not calm down, but Ms. Menaker continued to yell and ripped posters hanging in the administrator's office.

Ms. Menaker, 53, said in an interview that she had been quite involved in political causes before immigrating to the United States and had been arrested twice in Russia for her affiliation with religious groups and her underground-education efforts.

"The U.S. legal game is very unknown to me, but I am a fighter," said Ms. Menaker, who has three children and also works as a journalist for Russian publications and the California-based online periodical FrontPageMagazine.com, which is edited by the political activist David Horowitz. "I fought the KGB in Russia, and I see children of the KGB here, meaning people who will do everything to get power."

According to Ms. Menaker, the disciplinary officer told her that she was expelled until 2009, but Ms. Holmes said the administrator had only discussed that possibility with the student. Ms. Holmes said the final result would be determined in a disciplinary hearing on March 15.

Ms. Menaker's friction with faculty members, administrators, and pro-Palestinian groups began during a highly publicized clash between Muslim and Jewish groups on the campus in May 2002, when Ms. Menaker was accused of yelling at Palestinian activists and shouting racial slurs against African-Americans (The Chronicle, May 14, 2002). She denied that she had ever used slurs but conceded that she had spoken harsh words against pro-Palestinian demonstrators.

Following that altercation, the university rescinded financing for the General Union of Palestine Students, a pro-Palestinian student group. The administration also sent a warning letter to the Jewish student group involved.

Ephraim Margolin, a San Francisco-based criminal lawyer who is representing Ms. Menaker pro bono, said he believed the situation could be resolved amicably for both the university and Ms. Menaker.

Ms. Menaker said she hopes to return to the campus and finish her degree.

"Right now, I am very lucky because the teachers I had [at San Francisco] are so great," Ms. Menaker said. "It was such an opportunity to study, and I hope to complete it."
