The first to take the oath was Puri, who was elected from Uttar Pradesh. Three AAP MPs - Sanjay Singh, N D Gupta and Sushil Gupta - also took the oath.
Sushil Gupta took oath in English, while the others took oath in Hindi when the Rajya Sabha assembled after President Ram Nath Kovind's customary address to the joint sitting of Parliament.
