Khan, who is the owner of IPL team Kolkata Knight Riders, had angered Sena when he regretted the absence of Pakistani players, none of whom were picked up by the franchises in the auction held last month.
"As an Indian I'm not ashamed, guilty or unhappy about what I said neither am I sorry," Khan, who is in New York for the promotion of his upcoming film 'My Name is Khan', said.
The Shiv Sena has threatened to stall the screening of Khan's film, which will hit the theatres on February 12. The Maharashtra government has warned the Sena against creating trouble for the screening of the film and promised that adequate security would be provided to the theatres.
