US College Protests: How are the students' group involved?

On April 18, The police arrested about 100 demonstrators who were in support of Palestine at Columbia University. Now, the New York campus is witnessing a new protest encampment. Several protestors, over hundreds of protesters, are protesting in the demonstration, and many of them have been arrested in California and Massachusetts. 

The protests 

The conflict between Palestinians and Israel has been a striking force for the protest. The American public has been divided as per the response from the politicians, administrators, students, and faculty.
Take a look at all the groups in the protest. 

Student participants

The Columbia University Apartheid Divest has been the organi, ed of the protests held at Columbia. The Columbia University Apartheid Divest was founded in the year 1026 and stands as a self-proclaimed coalition of about 100 student groups
The group of students includes Muslim, Palestinian, and Jewish members as well. The group reactivated the coalition. It revived its divestment demands post the hostage. 

Jewish and Muslim prayers were organized by the Columbia students at the encampment. Various speeches were also delivered that condemned Zionism and Israel. The speeches applauded the armed resistance of Palestine as well. It was not able to cease investments by Columbia in the manufacturing of weapons or investments in firms that supported Israel's occupation in Palestine.
Mahmoud Khalis is the lead CUAD negotiator who converses with the officials of the university. Mahmoud Khalil is actually a Palestinian. As far as his educational background is concerned, he is a student at the Columbia School of International and Public Affairs pursuing post-graduation. 
There are two important lead student groups that are in coalition. These are the Students for Justice in Palestine and the Columbia chapters of Jewish Voice for Peace. These groups hold chapters across the nation. These have played an important role in the protests on the other campuses.
Both groups were suspended by Columbia in the month of November. Columbia said that they aided in setting up a protest that violated the event rules of the school. The non-profit New York Civil Liberties Union aided the students. The students are actually filing suits against the school, with the contention that Columbia actually did not follow its very own disciplinary procedures. Students are also of the view that the punishments by the school are disproportionate.
