Egyptian courts heard separate cases Monday - one against deposed President Hosni Mubarak and the other against top leaders of the Muslim Brotherhood.
Both are facing charges in the deaths of protestors who were demonstrating against their regimes when they were in power.
Meanwhile in the U.S., Egyptians launched new protests against the Brotherhood, expressing support for the Egyptian military leaders that removed them from power.
"It's not a coup it's a revolution," said protestor Samira Ibrahim. "We want to live in peace."
In Washington State, protestors marched to show solidarity with Egyptian Christians being targeted by the Muslim Brotherhood.
"We are enjoying the freedom of the U.S., but our friends, our brothers and sisters in Egypt continue to suffer for no reason other than being Christian," demonstrator Girgis Hafzalla said.
"The international community needs to know the Muslim Brotherhood is a danger. Egypt is better off without it," he continued.
Anti-Christian violence has calmed down in recent days, but at least 60 Coptic churches were torched or attacked by Islamists retaliating for the overthrow of the Brotherhood.
Last week, hundreds of Christians and Muslims marched in Washington, D.C. in protest of the U.S. government's support for the Islamist group.
