US homeland security secretary, Kirstjen Nielsen, has become the face of Trump’s “Zero Tolerance” immigration policy. This policy, implemented in April, has led to the separation of 2,300 children from their parents at the border with Mexico. Last month, Kirstjen Nielsen defended the policy to reporters at the White House. “We have to do our job. We will not apologize for doing our job,” she said. Many congressional Democrats called for her resignation, and some Republicans, as well as people from Trump’s own circle (including the First Lady), spoke against this “cruel” policy. After days of controversy, Trump signed an executive order to put an end to family separations. homeland security secretary ministre de la Sécurité intérieure / to implement mettre en oeuvre, appliquer / border frontière / to apologize s’excuser / congressional siégeant au Congrès / to call for réclamer / resignation démission / executive order décret (présidentiel).
