"Aapko tay karna hai ki Dilli mein sarkar Ramzadon ki banegi ya har**zadon ki. Yeh aapka faisla hai (you have to decide whether Delhi will get a government of those born of Ram or of those born illegitimately)," said the BJP MP from Fatehpur in Uttar Pradesh.
The 47-year-old Niranjan Jyoti joined the Modi government as a minister of state for food processing on November 9.
During the rally, the minister also attacked Robert Vadra, son-in-law of Congress president Sonia Gandhi, over his wealth.
