The meeting was one of the first that Mr Gallagher attended since announcing his candidacy last week and, similar to other meetings, he spent much of his speech addressing the 2011 race, which he lost after a controversial RTÉ Frontline debate. Last year, he won an apology and undisclosed settlement from RTÉ over a false tweet which was read out on air, as he struggled to explain his role in a Fianna Fáil fundraiser several years previously.
Mr Gallagher said that he wanted to build upon the work of President Michael D Higgins, who beat him in 2011.
Ms Freeman said that she invited service users and providers to the Oireachtas, founded and chairs the first Oireachtas Mental Health Committee, and passed a motion through the Seanad stopping children from being placed in adult psychiatric wards.
Ms Freeman was asked by Sinn Féin councillor Paul Hayes if her personal views would stop her from signing a bill that she disagreed with into law.
