Student activist Mohsen Mahdawi has attended his graduation from Columbia University, weeks after his release from federal custody.

Mr. Mahdawi, who led pro-Palestinian demonstrations at Columbia University, was released from detention late last month and allowed to travel from Vermont to get his diploma.

Columbia University student Mohsen Mahdawi, recently detained by federal immigration officials for his pro-Palestinian activism, walked across a graduation stage on Monday, blowing a kiss, bowing, and flashing peace signs to a roaring, largely standing crowd.
