Nigel Farage is set to discuss the imprisonment of Lucy Connolly at a hearing in US Congress next month.
The mother was behind bars for more than a year after admitting making the inflammatory post on X in the wake of the Southport attacks in July last year.
Connolly pleaded guilty to a charge of inciting racial hatred and was handed a 31-month sentence in October, having been held on remand following her arrest last August.
The Reform UK leader is due to testify to member of Congress in Washington about threats to freedom of speech and expression in the UK, The Telegraph reported.
Farage said the situation surrounding 'political prisoner' Connolly will be a 'central point of what I'm discussing'.
