Controversy
During campaigns for the 2016 US presidential election, Mondelēz and Rosenfeld were criticized by Republican candidate Donald Trump[22] and Democratic candidates Hillary Clinton[23] and Bernie Sanders[24] for outsourcing approximately 600 U.S. jobs from Chicago to Salinas, Mexico,[25] prompting the Oreo Boycott.[26] Worker pickets have also taken place at various events Rosenfeld has attended,[27] in addition to outside her own home.[28]
