Garg has accused Arvind Kejriwal of horse trading last year to form the government. He had recorded his telephonic conversation with Kejriwal which was leaked to media few days back.
He also feigned ignorance on how it went public saying he had e-mailed it to party leader Kumar Vishwas.
Vishwas later hit back at Garg alleging he was trying to blackmail him in return for a party ticket.
Garg also served a legal notice to AAP leader Kumar Vishwas on Monday for calling him a black-mailer and an opportunist.
In the notice, Garg stated that Vishwas’s remarks has tarnished his image and has asked him for an unconditional apology within 15 days from the receipt of the legal notice. The former AAP MLA asserted that if Vishwas fails to tender apology, he will initiate suit for damages and file a criminal case.
Vishwas had alleged Garg of blackmail him in return for a party ticket in the Delhi Assembly election.
