Mexico’s president confirmed Tuesday that federal prosecutors had tried to get an arrest warrant for former Treasury and Foreign Relations Secretary Luis Videgaray, but said a judge rejected the request. Videgaray, currently a faculty member at the Massachusetts Institute of Technology’s Sloan School of Management, is considered the political figure closest to former President Enrique Peña Nieto, in whose 2012-2018 administration he served. President Andrés Manuel López Obrador said Tuesday he did not know what the charges were because he maintains an arms-length relationship with the independent attorney general's office, though he said he had read they included a charge of treason.
