In 1918, Khanna participated in the
Delhi Congress as a volunteer of "Shahjahanpur Seva Samiti". Bismil was his group leader. Khanna, along with other volunteers were selling a book entitled "Amrika Kaise Swadhin Hua?" (en. How America Became Independent?) outside the Congress Camp. The police raided the camp but the unsold books were removed from the camp by Bismil immediately and nobody was arrested. Likewise, Khanna also participated in the 1921
Ahmedabad Congress where the proposal of "Poorn Swaraj" was placed before the delegates. When Maulana
Hasrat Mohani spoke in favour of this proposal and
Mohandas K. Gandhi opposed it, Khanna, Ashfaq and Bismil stood up in favour of Mohani and the audience became totally against Gandhi. The proposal was accepted and
Non-Cooperation Movement was announced to be moved throughout the country under the leadership of Gandhi. When Gandhi withdrew from the movement after
Chauri Chaura incident, Khanna started agitation against him along with
Ram Prasad Bismil. He also went to
Gaya with his team of young volunteers and condemned the decisions of Gandhi in the Congress. When
Subhas Chandra Bose and Pandit
Jawahar Lal Nehru supported their stand Gandhi wrote a very strong letter to Nehru not to support these miscreant elements in the
Indian National Congress. ==Switch to HRA==
