Story highlights The MoveOn forum will be held in mid-November

Democrats have officially sanctioned six debates

Los Angeles (CNN) Amid public pressure to expand the debate calendar, the Democratic National Committee has given the green light to a MoveOn "forum" that will reunite party contenders on one stage.

The forum, which is expected to take place in mid-November, will feature Democratic hopefuls responding to pre-recorded questions from members of MoveOn, the progressive advocacy group. All Democratic candidates have been invited, including the activist and academic Lawrence Lessig, though so far only Vermont Senator Bernie Sanders has confirmed that he will attend.

The forum is not a debate: the candidates will not respond to nor engage with one another.

The additional session comes in the wake of intra-party sparring over the DNC's decision to sanction just six primary debates this election cycle, with only four taking place before the Iowa caucuses.

The most vocal critic of the limited schedule has been Democratic Vice Chairwoman Tulsi Gabbard, who claimed that she had been dis-invited from the party's first showdown in Las Vegas after calling for additional debates.
