The Congress general secretary said the party was not scared of Ramdev and is holding discussions with him.
"If Congress was scared, Ramdev would have been put behind bars. There is no fear that is why he is out in the open and there are discussions with him," he said.
The party has differed with the government`s extraordinary step of rushing four senior ministers to the airport yesterday to talk to the yoga guru.
