Maher attempted to organize several demonstrations after April 2008. However, his efforts were hindered both by interference from Egyptian security forces and internal divisions within the April 6 movement. In June 2010, Maher helped organize a protest against the killing, by Egyptian police, of Khaled Said, a young resident of Alexandria. Maher has expressed support for the potential bid of Mohamed ElBaradei for the Egyptian presidency.
