In particular, one student photographer, Tim Tai, was seen in a much-watched video arguing with protesters who surrounded him and pushed him back. Toward the end of the video, the person shooting it identified himself to Ms. Click as also being with the media, and when he refused her demands that he leave, she yelled: “Who wants to help me get this reporter out of here? I need some muscle over here.”

In a statement on Tuesday, Ms. Click said, “I regret the language and strategies I used, and sincerely apologize to the M.U. campus community, and journalists at large, for my behavior, and also for the way my actions have shifted attention away from the students’ campaign for justice.” She said she had called the journalists involved to apologize, personally.

Mr. Tai said he accepted the apology.

“I never had ill will toward her and I felt bad when I heard she’d been getting threats,” he said. “I think this has been a learning experience for everyone involved, myself included, and I hope this blows over for both of us.”

On Tuesday, leaders of the group that organized the protest, Concerned Student 1950, distributed leaflets saying that “media has a First Amendment right to occupy campsite.”
