She is no fan of the ag giant’s pending mega-merger.

Back in September 2016, US agribusiness titan Monsanto and German chemical conglomerate Bayer agreed to a $66 billion merger, making way for a globe-spanning firm with huge shares of the world’s seed and pesticide markets. The deal remains unconsummated, still under scrutiny by antitrust authorities. Donald Trump signaled readiness to bless the deal before taking office, but his administration has been pretty silent about it since. 

Enter Trump’s nemesis, Sen. Elizabeth Warren (D.-Mass.). In a recent speech before the Open Markets Institute, Warren denounced rising levels of corporate consolidation—massive companies merging into vast market-dominating entities that invest a share of their profits in lobbying and financing campaigns, shaping the political system to their own ends. 

At one point, Warren turned her attention to one of the most consolidated sectors of the US economy: agribusiness. And she called on the Trump administration to nix Bayer-Monsanto. “If the Bayer-Monsanto merger is approved, one gigantic company would supply one-quarter of the entire world’s seeds and pesticides,” she noted. (Her math matches up pretty closely with my assessment).
