US Deputy Secretary of State William Burns will meet later on Monday with Saad Katatni, the leader of the Muslim Brotherhood's Freedom and Justice Party (FJP), at his detention, said the interim president's media advisor.
In a press release, Ahmed Meslimani said Burns had acquired the necessary permits from the authorities concerned.
Katatni, the former parliament speaker, is held in custody on charges of inciting the killing of protesters outside the Brotherhood's main headquarters in Cairo's Moqattam district on June 30.
At least nine people were killed in clashes between Brotherhood supporters and protesters near the premises.
Meslimani did not clarify whether Burns would be accompanied by others.
Muslim Brotherhood deputy leader Khairat al-Shater has reportedly refused to meet a delegation of Western and Arab mediators, including Burns, late Sunday.
"Shater refused to meet them or listen to anyone in the delegation," Mohamed al-Beltagi, a senior leader of the Muslim Brotherhood and its Freedom and Justice Party (FJP), told the Anadolu Agency.
"He told them to go and talk to the legitimate President Mohamed Morsi."
Earlier a US Embassy diplomatic source told the AA, Burns, Qatari Foreign Minister Khaled bin Mohamed al-Attiya and United Arab Emirates Foreign Minister Sheikh Abdullah bin Zayed al-Nuhayan might visit Morsi after failure to meet al-Shater.
The Egyptian capital has been abuzz with diplomatic activity in recent days, with officials coming from four continents for talks aimed at resolving Egypt's political impasse.
Pro-Morsi demonstrators have been staging daily mass rallies and sit-ins nationwide since he was ousted by the powerful military on July 3 following mass protests against him.
The two largest sit-ins are in Cairo's Rabaa al-Adawiya and Nahda squares.
