Breaking his silence on the defeat in three northeast states, Rahul Gandhi on Monday said the Congress was committed to winning back the people's trust and hit out at the BJP, accusing it of "usurping" power through proxy in Meghalaya and using "big money" to create an "opportunistic alliance". "The Congress party respects the mandate of the people of Tripura, Nagaland and Meghalaya," Gandhi said on Twitter two days after results of assembly elections were declared.
