President Trump commented on the murder trial of Lindsay Clancy, a Massachusetts mother accused of strangling her three young children in January 2023, after a mistrial was declared when the jury deadlocked 11-1 in favour of acquittal on grounds of insanity. Trump said Clancy would still "pay a price," predicting either a mental institution or jail, while a retrial is expected. The case has become highly politicised, with Republican lawmakers, including Ron DeSantis, Nancy Mace and Mike Lee, condemning the outcome and criticising the lone holdout juror's colleagues, while Democratic figures have largely stayed silent.

Clancy's defence did not dispute that she killed Cora (5), Dawson (3) and Callan (8 months), but argued she was not criminally responsible due to postpartum psychosis, exacerbated by 13 psychiatric medications prescribed in the months before the killings. Judge William Sullivan declared the mistrial after nearly a week of deliberations by a jury of nine women and three men, with defence lawyers seeking to have the dissenting juror removed. Clancy is due back in court on 29 September for a status hearing and further proceedings ahead of a likely second trial.
