The Trump administration is escalating pressure on European companies to comply with a US executive order banning diversity, equity, and inclusion (DEI) programs in federal contracts. Letters sent by American embassies warn that these rules apply even if businesses are not based in the United States but provide services or supplies to US government agencies. The communication includes a questionnaire requiring recipients to certify they do not operate DEI programs that violate anti-discrimination laws. The US Department of State is demanding this certification as part of payment decisions for government contracts and emphasizes that non-compliance could lead to legal repercussions under the False Claims Act.
