Raja, however, met Kejriwal at the Delhi Secretariat with his daughter and Jawaharlal Nehru University (JNU) student activist Aparajitha.
Raja added that Aparajitha had not come to meet Kejriwal as his daughter but as a student leader in support of Kanhaiya Kumar, who is on bail after being in jail on sedition charges.
Both Kanhaiya Kumar and Aparajitha are members of the CPI-affiliated All India Students Federation (AISF).
Asked if the CPI had any larger political plans for Kanhaiya Kumar, Raja replied: "Plans? We have no plans."
