2019 Argentine general election

At a conference in Washington, D.C., Sergio Massa, candidate for the Argentine Chamber of Deputies for Frente de Todos, the coalition of candidate Alberto Fernández, says Fernández's position on Venezuela is clear and that keeping silent about the situation in Venezuela is to "become an accomplice of the government [of Maduro]". He also is the first member of Fernández's party to describe Venezuela as a "dictatorship".

Massa buscó calmar a los mercados en Washington con un mensaje moderado y se pronunció en contra de la dictadura venezolana
