"Hum inki baat ka samarthan karte hain aur maang karte hain sarkar se ke Prashant Bhushan ke khilaf CBI ki jaanch honi chahiye (We agree with his suggestion and demand that Prashant Bhushan should be probed by the CBI)," Kejriwal said.
The Congress had raised questions over the property held by Bhushan in Himachal Pradesh after Kejriwal and his team alleged corruption in property acquisitions by Sonia Gandhi's son-in-law Robert Vadra in Gurgaon.
Bhushan, a Supreme Court lawyer, has been a member of India Against Corruption (IAC) since the movement started.
Allegations have earlier been raised against Prashant Bhushan's father and IAC member Shanti Bhushan, blaming him for evasion of property taxes.
