The allegation comes in the wake of a sting operation by media portal mediasarkar.com, which showed some AAP members allegedly accepting donations without proper verification.
"I am told Rs.1,400 crore have been distributed to a few media houses. Who are these media houses?" tweeted AAP chief Arvind Kejriwal.
The party also held a press conference in Delhi on Sunday in which it gave a clean chit to all its members featured in the video and reiterated that it will sue the media portal's chief executive officer Anuranjan Jha as well as some other media houses.
"We will soon be filing civil and criminal defamation cases against the media portal and some channels," lawyer Prashant Bhushan said.
The sting that came out on Thursday showed AAP leaders, including Shazia Ilmi, candidate from south Delhi's R.K. Puram, accepting donations without proper verification days before the December 4 Delhi assembly polls.
