"The question is whether the Indian embassy in Pakistan facilitated this event...whether they helped this gentleman (Vaidik) in anyway," Rahul Gandhi said, speaking to reporters here.
He also described Vaidik as a Rashtriya Swayamsevak Sangh (RSS) man, which he said was a "known fact".
The 69-year-old Vaidik's meeting with Hafiz Saeed in Pakistan has sparked off a major row with the Congress seeking to pin down the Narendra Modi government by asking if he was sent as an emissary even as the ruling BJP has distanced itself from the meeting, asserting Saeed was a "terrorist".
Hafiz Saeed was the mastermind behind the 26/11 Mumbai terror attack, in which one Pakistani terrorist, Ajmal Amir Kasab, was caught alive. He was tried and executed later.
