Both have, however, clarified that they have not resigned from the party, but from the posts they held.
"Rumours about my quitting AAP are baseless. I am very much with the party and committed to working for it harder than ever," Yadav tweeted. However, when asked why he quit as the PAC member, he declined to comment.
Party spokesperson and Delhi unit secretary Dilip Pandey clarified that the duo had resigned as members of the PAC and NE and not from the party.
"@AapYogendra and @naveenjaihind are still with @AamAadmiParty... And resignation given from PAC & NE resp. To be discussed in NE meeting," Pandey tweeted.

Senior party leader and PAC member Sanjay Singh told reporters that Yadav's resignation will not be accepted.
Yadav, who unsucessfully contested from Gurgoan parliamentary seat, is a senior leader and member of the supreme decision making body, the PAC. He is also party's Haryana incharge.
Jaihind, who has been associated with the party even before it was formed, is Haryana convenor and was handpicked by party chief Arvind Kejriwal to contest against Chief Minister Bhupinder Singh Hooda's son Deepender Singh Hooda from Rohtak.
"We had a meeting with the volunteers who were of the opinion that party decisions should be taken after consultations within members.
"Yogendra Yadav lodged a complaint against me and PAC served me a notice, in Arvind Kejriwal's absence, for instigating the volunteers. Today Yadav demanded that action should be taken against me in 48 hours," Jaihind said, adding that he received a mail from the party on May 28.
He has also responded to the show-cause notice and termed the allegations as "baseless".
