Sinha also wondered who gave the advise for the CBI raid at the office of Principal Secretary Rajendra Kumar.
"Wonder who advised for the strike, that too while Parliament was in session. After all, CM (Kejriwal) is not only very popular but masses' favorite too," he said.
"Good sense must prevail upon those who have brought embarrassment to our people and our leadership...That too at this juncture," he added.
In another tweet, Sinha said: "Don't approve of avoidable language of Delhi CM about our dashing dynamic action hero PM. But need to look within. How why & who started it?
