He apologises for "any hurt or offence caused". He later states on Twitter that he is "mindful of unintended hurt caused to victims' families" and offers to meet with Kingsmill relatives. Mr Ó Muilleoir also deletes his retweet of the video and apologises. Sinn Féin MLA Colm Gildernew posts support for Mr McElduff, saying "it is my belief that Barry would never intentionally insult or hurt any victim of this or any other conflict".

Mr McElduff later meets with the Sinn Féin leadership in Belfast to explain his actions. He announces he has been suspended "from all party activity for a period of three months" and again apologises. Northern leader Michelle O'Neill says during the meeting she "made it clear to Barry that his tweet was ill-judged, indefensible and caused hurt and pain to the victims of Kingsmill". Unionists and victims criticise the sanction amid widespread media coverage.
