He spoke at an agriculture conference in December 2015, and emphasized that his government fully supports the International Center for Agricultural Research in the Dry Areas 's initiative to “expand wheat production in the country to enhance national food security and reduce dependence on increasing wheat imports.” In June 2016, he caused controversy when he called Ahmed Baba Ould Azizi, President of the General Confederation of Employers of Mauritania, "a terrorist, worse than Al Qaeda and Daesh together." He resigned from the premiership on October 29, 2018.
