CAIRO – Saad Eddin Ibrahim, the Egyptian American sociologist and activist, asserted that the US Administration would never have accepted Gamal Mubarak to succeed his father as Egypt's President, A-Youm Al-Sabie website reported on Monday. "The ousted Mubarak had promised the US Administration to step down on January 29, but he didn't," Ibrahim told CBC, a recently launched private satellite channel in an interview on Sunday night. "After January 29 President Barack Obama urged Mubarak to carry out genuine reforms, to which Mubarak responded at the beginning". According to Ibrahim that was the last phone call Obama had made with Mubarak before the latter stepped down on February 11," he added. Ibrahim said that he spent the 18 days of the Egyptian revolution at the White House as he was invited by Obama's advisors to join the team that monitored developments in Egypt during the revolution. "I told the US Administration that Mubarak was not a straightforward man. He failed to keep his promises to the people." Ibrahim added that Mubarak pledged not to run for another term of presidency, but he kept renewing one tenure after another eventually ruling the country for 30 years. Ibrahim added that Gamal Mubarak and his brother Alaa have ironically been detained in the same cell where he (Ibrahim) had been jailed during Mubarak's rule. Gamal and Alaa who have been detained pending investigations are facing graft and corruption cases. They alone with their father will be tried on August 3. Mubarak was admitted to Sharm el-Sheikh Hospital in March where he is being treated till date from cardiac problems. He too is facing charges of graft and political corruption.
