Chief Minister Siddaramaiah, his Deputy D.K. Shivakumar were seen protesting by wearing a black mask and covering their mouth.
All the MLAs, ministers, MPs and leaders are taking part in the protest.
DyCM and state Congress president Shivakumar charged the BJP government at the Centre with attempting to conspire and end the political career of Rahul Gandhi.
The silent protest is being observed under the leadership of AICC President Mallikarjun Kharge.
Urging the party workers to participate in large numbers, Shivakumar on Tuesday said that Rahul Gandhi has never damaged the prestige of the country. There is a conspiracy to end his political career on the pretext of the speech he delivered in Karnataka. "We condemn this. The message has to be sent to the Opposition and across the country to stand with Rahul Gandhi who is standing for truth and the country," he stated.
Unable to tolerate the success of Rahul Gandhi's Bharat Jodo Yatra and big success in Karnataka, his membership of Parliament has been suspended. The Congress has won in all constituencies where Rahul Gandhi took out Pada Yatra, Shivakumar had said.
The suggestion had come to take up Bharat Jodo Yatra from East to West in India. BJP after seeing his popularity, success is conspiring against him, Shivakumar maintained.
