The International Criminal Court issued an arrest warrant for the Sudanese president on charges including genocide in 2009, but the African Union has ignored the warrant and al-Bashir has freely travelled outside Sudan several times since then.
John Prendergast of the Enough Project, which organized a National Day of Action on Friday to advocate for emergency aid for the people of Sudan, was the first to be detained. NAACP president Ben Jealous, Martin Luther King III and others soon followed, then Clooney and his father, Nick.
"They need to stop using rape and food as weapons in Sudan," Jealous told reporters as he was led away.
When it was Clooney's turn, a reporter asked what he thought about being arrested with his journalist father.
"Well, it's not actually a humiliating thing to be arrested no matter what you do, but I'm proud to be standing here with my father," he said.
On Thursday, Clooney spoke to the U.S. Senate foreign relations committee, telling members there is a campaign in Sudan of "murder and fear and displacement and starvation."
He urged President Barack Obama to help open a humanitarian corridor in Sudan to allow aid to reach the south before the rainy season. The actor told Friday's rally the lives of thousands of people are at risk once the rains come.
I hope this get's the attention he wants.. it's a good cause.
