 Khalil was active during the 2011 Egyptian revolution and its aftermath.In May 2011 Khalil spoke out for a second wave of protests in support of a "Friday of rage" against the Supreme Council of the Armed Forces (SCAF).In an editorial in "The Guardian", Khalil's criticisms of the SCAF focused on rumors about pardoning Mubarak and members of his regime, physical or violent reactions of security forces during protests, the army's use of military trials against civilians, use of trials against protesters and 'normal citizens', and he also noted the prior successes which resulted from large protests in Tahrir Square.
