Rajasthan Governor Kalraj Mishra today shot off a strongly-worded letter to Chief Minister Ashok Gehlot, who, along with his around 100 MLAs, protested at his official residence in Jaipur, demanding an urgent assembly session amid a raging political crisis. "Who should I speak to for my security?" the Governor said, reacting to the Congress leader's remark that his government will not be responsible if people of the state "gherao" Raj Bhavan.
