Mexican President Claudia Sheinbaum rejected a request from magnate Ricardo Salinas to negotiate billions of dollars in tax claims the government alleges his companies owe. 
Sheinbaum said Friday she would not engage in what she called “negotiations in the dark” over the tax disputes, worth up to 74 billion pesos ($4 billion). Salinas has been organizing a political movement in opposition to the leftist Mexican government. 
“The point is that there are things that are not negotiable, because it’s not political, it’s the law,” Sheinbaum said during her daily press conference.
