The USDA’s $4 billion Farmers to Families Food Box Program began requiring that all boxes include a self-praising letter from the president, in both English and Spanish, a month ago — setting off a rash of criticism that Trump is leveraging taxpayer resources to bolster his reelection campaign.

But as election day nears, nonprofits distributing the boxes are becoming increasingly worried about unwittingly engaging in political activity, according to interviews with more than two dozen people involved in the program. They’re ramping up efforts to remove the letters — and some are adding letters of their own explaining that the boxes are unrelated to the campaign.

“I view it as propaganda,” said Melissa Acedera, founder of Polo’s Pantry, a mobile food pantry that aids the most vulnerable in Los Angeles, including those who are homeless.
