Microsoft is weighing disciplinary measures for employees who occupied President Brad Smith’s office on Tuesday in protest of the company’s relationship with the Israeli government during its war in Gaza.

The employees, members of a group that calls itself No Azure for Apartheid, broadcast live video of themselves entering Building 34 on Microsoft’s Redmond, Wash., campus and hanging banners inside Smith’s office. A spokesperson for the group confirmed that several Microsoft employees participated in the takeover of Smith’s office and were arrested.
