Immediately following her election as a TD in 2020, a number of controversies arose from Cronin's past. It emerged that in 2019, Cronin tweeted that "sinister" Mossad interference in the 2019 United Kingdom general election was responsible for the defeat of Jeremy Corbyn. Cronin added that Corbyn was a "principled man" victimized by "lies, deceit, fake news, and the sinister activities of the Mossad Secret Service", and that the alleged Mossad actions were "blatant as f***." After being criticized by the Israeli embassy in Ireland for a "history of paranoid, hate-driven conspiracy theories," Cronin backtracked, calling her comments "throwaway remarks." Sinn Féin issued a statement stating that Cronin's remarks "do not represent the views of Sinn Fein".[4][5]
Older tweets surfaced in the following days where she claimed Israel had "taken Nazism to a new level", linked Hitler to the Rothschild family, compared a picture of monkeys working on computers to the Israeli Embassy and suggested Irish judges could be paedophiles and promoted conspiracy theories about the harmful effects of water fluoridation.[6][7] Her comments were condemned by TaoiseachLeo Varadkar and by Maurice Cohen, chair of the Jewish Representative Council of Ireland who characterised them as "inaccurate, anti-Semitic and racist”.[8]
Separate to her conduct on social media, it was also after her 2020 election that it came to light that Cronin and her husband Donal built a €1,000,000 home in Kildare in 2002 knowing that they did not have full planning permission to do so.[1] When Cronin and her partner were subsequently caught by Kildare County Council, they lobbied then Minister for Finance Charlie McCreevy to personally intervene, which he did do. Cronin issued a statement in which she declared "In relation to my former home, there was an issue in respect of planning and this matter was settled in court, with the consent of Kildare County Council. This dates back almost two decades and is a matter of public record. As a public representative, I will always answer for matters relevant to my role, but matters relating to my family and my personal life are not relevant to my role as a TD."[9]
