"I had learnt from media reports that Maderna is not keeping well, so I decided to pay a courtesy visit to him," Rathore told reporters after the meeting.
"The visit has nothing to do with politics or exploring the possibilities of Maderna (Congress) joining BJP," he said.
However, he said, "I hope after the manner in which the Congress treated Maderna and MLA Malkhan Singh Bishnoi (another accused in Bhanwari murder case and is currently in jail), they won't support Congress presidential candidate Pranab Mukherjee and support BJP's choice (P A Sangma)."
Rathore, who was also in the Jodhpur Central jail, said he used to spent time with Maderna in the prison and has sympathy for him for the treatment meted out to him by Congress.
Rathore was released from the jail in May.
