MEXICO CITY - Mexico's President Enrique Pena Nieto asked a high-level US delegation on Friday to quickly reunite separated migrant families and warned of 'hatred and racism' after an attack on a 92-year old Mexican man in California. Pena Nieto said in a statement that the US delegation, which is being led by Secretary of State Mike Pompeo, agreed to constructively move forward the talks to revamp the North American Free Trade Agreement.
