Cairo: Two leading US Senators have urged Egypt's leaders to engage in an "inclusive" dialogue with supporters of ousted president Mohamed Mursi as a way out of the crippling political crisis.
Republicans John McCain and Lindsey Graham met earlier with army chief Abdel Fattah al-Sisi and other interim leaders amid an intense diplomatic push to end the stalemate.
"The people who are in charge were not elected, and the people who were elected are now in jail."
"Democracy is the only viable path to stability," said Senator McCain, a former presidential candidate, calling for "an inclusive political process in which all Egyptians are free to participate."
Both lawmakers referred to the military's July 3 removal of Dr Mursi as a "coup," something their government has been reluctant to do as it would have legal implications for the $US1.3 billion ($A1.46 billion) dollars in US aid to Egypt.
"The people who are in charge were not elected, and the people who were elected are now in jail," Senator Graham told reporters.
The senators called for release jailed Muslim Brotherhood leaders, including Dr Mursi.
"In a democracy, you have to talk to each other. It is impossible to talk to somebody in jail," Senator Graham said.
"The judicial system will deal with this in the future. Jailing opposition is not the exercise of a legitimate power," he said.
Dr Mursi has been formally remanded on suspicion of offences committed when he escaped from prison during the 2011 revolt that toppled president Hosni Mubarak.
Prosecutors have also set an August 25 date for the trial of the Muslim Brotherhood Supreme Guide Mohammed Badie and his two deputies.
Egypt's political crisis, sparked by the military's July 3 overthrow of Dr Mursi, has paralysed the country and deepened political polarisation and social divisions.
Mursi loyalists, mostly Brotherhood members, say the ouster of the country's first freely elected president violates democratic principles and nothing short of his reinstatement would end their sit-ins.
The interim leadership says there is no turning back on the army-drafted roadmap that provides for new elections in 2014.
More than 250 people have been killed since Dr Mursi's removal.
