Sinn Fein Stormont leader Michelle O'Neill has warned party member Mairtin O'Muilleoir that he must be "more responsible" on social media after he retweeted a video posted by colleague Barry McElduff with a Kingsmill-branded loaf on his head on the anniversary of the Kingsmill massacre.
Abstentionst West Tyrone MP Barry McElduff today resigned over the tweet.
Ms O'Neill indicated that no further action would be taken against Mr O'Muilleoir.
"That is the matter dealt with," she said.
Sinn Fein's former Stormont finance minister, O Muilleoir, apologised last week for retweeting the video.
Unionists have criticised Sinn Fein for not taking disciplinary action against Mr O Muilleoir.
Ulster Unionist Party leader Robin Swann said: “As a former executive minister, Máirtín Ó Muilleoir needs to explain himself. As a self-proclaimed social media guru he knew exactly what his ‘like & retweet’ signalled. He cannot escape the spotlight. And what has the leader of Sinn Féin in Northern Ireland, Michelle O’Neill, got to say about this? She has been conspicuously silent.”
Sinn Fein has said it accepted the South Belfast MLA's explanation for the retweet.
Mr Ó Muilleoir said that when he saw the original tweet from Mr McElduff he viewed it as “being wholly apolitical and retweeted it on that basis”.
“Once it was pointed out that the tweet had offended and hurt people and that Barry had rightly deleted his tweet I retweeted his apology and, of course, apologise unreservedly for the pain and hurt caused by my retweet,” added Mr Ó Muilleoir.
