The group is a platform used by the party's state unit to invite media for press conferences and other events.
"I apologise for the incident. We have already removed the office bearer from the group," Sunil Kawathankar, state party spokesman, who is the administrator of the group told PTI.
He said the member was immediately removed from the group after the porn clip he had posted accidently was brought to his notice.
The member is a former state general secretary of Goa Pradesh Congress Committee.
