Speaking to reporters after the PAC meeting, Deputy Chief Minister Manish Sisodia said the party leadership was upset with both Khan as well Vishwas for airing their differences in public.
He said the PAC has accepted Khan's resignation.
"Arvind ji is upset with both Kumar and Amanatullah. The PAC also discussed Vishwas' absence from the meeting. Even he (Vishwas) has been giving interviews and releasing video. The party is also unhappy with this.
The deputy chief minister said such developments were denting the party's image and affecting the morale of volunteers, while "warning the party leaders not to air their grievances in public, but at appropriate party fora."

Remaining defiant, Khan, however, said he stood with his remarks against Vishwas.
"Kumar Vishwas is an RSS-BJP agent and Arvind ji will soon realise it. He (Vishwas) talks about disconnect between party volunteers and leadership, but he had invited (former Delhi Commissioner) B S Bassi and (National Security Advisor) Ajit Doval for his birthday party.
In a major rejig last year, Khan had made it to the Political Affairs Committee (PAC), party's top decision making body.
He had yesterday claimed that poet-turned-politician Vishwas was calling MLAs to his residence and coaxing them to rebel against Kejriwal or to join the BJP.
His allegations were ridiculed by senior AAP leaders, including Chief Minister Arvind Kejriwal.
Meanwhile, senior AAP legislators have demanded expulsion of Khan from the party. It is learnt that a few MLAs of the party also signed a letter, urging the top leadership to expel the Ohkla MLA. A separate letter, with the same demand, has been released by a Punjab MLA of the party.
Earlier, Vishwas had differed with Kejriwal on the issue of electronic voting machines (EVMs). He had refused to attribute the AAP's recent poll upsets to alleged manipulation of EVMs and had instead stressed on the need to introspect.
Earlier in the day, Kejriwal met Sisodia at his residence. Sisodia and senior party leader Sanjay Singh also met Vishwas at his residence in Ghaziabad.
