The United States on Monday sanctioned the wife of Brazilian Supreme Court Justice Alexandre de Moraes, marking a further escalation in the diplomatic clash between Washington and Brasília over the prosecution of former President Jair Bolsonaro. The move broadens earlier sanctions imposed on Justice de Moraes himself and extends to Lex Instituto de Estudos Jurídicos, a financial entity controlled by Barci de Moraes and relatives. De Moraes has emerged as one of Brazil’s most influential judges, supervising a number of lawsuits against Bolsonaro and his allies. Previous administrations have typically reserved Magnitsky sanctions for individuals linked to severe abuses, including war crimes or extrajudicial killings. The dispute has been inflamed by Trump’s personal relationship with Bolsonaro, whom he has repeatedly referred to as a political ally.
