The 'Halla Bol' campaign was launched by Rajasthan BJP chief Satish Poonia who said his party has decided to corner the state government on all public interest issues.
The opposition party's decision comes days after an "amicable resolution" of the nearly month-long political cisis in Rajasthan.
The BJP asked its legislators to come to its Jaipur party headquarters on Thursday instead.
Gehlot has accused the BJP of trying to destabilise the state government by trying to poach MLAs.
The digital poster, released on Social Media by Khan who is a known Raje loyalist, has angered many BJP workers who have started trolling Khan.
Poonia said that if Rahul Gandhi becomes the Congress chief again, 'it is a matter of entertainment for the country'.
Poonia went for testing on Sunday soon after a person present in the final rites of ex-state BJP chief Bhanwarlal Sharma tested positive on the same day and his reports came negative on Monday.
BJP state president Satish Poonia consoled Sharma’s family members at his residence and termed the death as a personal loss for him and the party.
Assembly speaker CP Joshi, after hearing Balveer Luthra's statement, said that this case should be investigated thoroughly.
