Texas Republican Senator Ted Cruz is accusing the Mexican government of targeting American oil and gas companies. Cruz brought up the matter this week in a Foreign Relations committee hearing. Mexican regulators recently shut down three privately owned fuel storage terminals, including one owned by Texas-based Monterra. Cruz says this action undermines the U-S-M-C-A trade agreement. He's urging the White House to do something about what he describes as Mexico's pattern of discrimination against American companies.
