A senior French judge warned Tuesday against “unacceptable” foreign interference after the U.S. reportedly considered sanctioning members of France’s judiciary.

“If such facts were true or were to materialize, they would constitute unacceptable and intolerable interference in our country’s internal affairs,” Peimane Ghaleh-Marzban, president of the Paris court that handled a contentious case involving far-right chief Marine Le Pen, said in an inaugural speech to new magistrates, according to AFP.
