Across the country, collections are popping up to help Transportation Security Administration officers who have been without full pay for more than a month due to the partial government shutdown affecting the Department of Homeland Security.

The charity World Central Kitchen, more accustomed to feeding those in war zones and disaster areas, started providing meals to Washington, D.C.-area airports after many TSA officers missed their first full paycheck. On Thursday, Feeding San Diego began distributing 400 boxes with pasta, beans and peanut butter as well as fresh produce like strawberries and potatoes to affected agents near the airport after a request from TSA and the San Diego County Regional Airport Authority.

Nonprofits are stepping in to help and coordinating closely with airports and local TSA offices because ethics rules around giving gifts to federal employees make it difficult for those affected by the shutdown to receive help directly.
