The businessman has hit out at Mr Kejriwal over his comment in the Delhi Assembly suggesting that Prime Minister Narendra Modi knows Mr Vadra "will eat him alive" if he went after him.
"Robert Vadra seems to be the most referred name in the dictionary of Delhi CM. His remarks 'Vadra will eat him alive' depict a strange obsession for me," Mr Vadra writes in his post.
"I would humbly request our Delhi CM to come and speak with me directly, for all the grudges he has against me, instead of inciting other people against me. My best wishes to our Delhi CM, in all his endeavours."
Mr Kejriwal is among those who have accused Mr Vadra of benefiting from land deals made in Haryana when the previous Congress government was in power for 10 years. The deals have been held up by the BJP and AAP during poll campaigns and in parliament as proof of massive corruption on Congress watch.
