In a communication, the MHA asked the Arvind Kejriwal-led party to explain certain fundings from abroad after suspecting that it might have violated FCRA provisions.
The MHA official said the communication to the AAP was part of its "routine" queries sent to a few other political parties regarding overseas funding to them.
The official made it clear that it was not a show cause notice and a decision on it would be taken only after the AAP submits its reply.
