The U.S. ambassador to Mexico, Ken Salazar, said on Wednesday that the country is not safe and criticized the previous president for a failed security policy and refusing to accept American assistance. "The reality is that at the moment Mexico is not safe," Salazar said during a press conference at his residence in Mexico City. The ambassador criticized former President Andres Manuel Lopez Obrador directly, saying security coordination between Mexico and the U.S. had suffered during his term.
