A WEEK ago the Tánaiste, Simon Harris, stood up in the Dáil during a debate on – what else? – housing. He used the occasion to criticise Sinn Féin for receiving financial contributions from the US through its US fundraising arm, Friends of Sinn Fein. In all, Sinn Féin raised €366,000, the bulk of that said to come from builders and construction companies in the US. Simon took a seriously dim view of that.
