2016 review of the HSUS Farm Animal Protection Campaign, ACE cited their strengths as their large reach, strategic approach, and long track record of legal work, corporate outreach, and meat reduction programs. ACE stated that their primary concern with the Farm Animal Protection Campaign was that it was unclear the extent to which their budget comes from the HSUS general budget, and whether small donations to the Farm Animal Protection Campaign would be fungible with other HSUS activities. In February 2018, ACE rescinded their recommendation of the HSUS Farm Animal Protection Campaign following allegations of misconduct from both the former president of HSUS and the former vice president of the Farm Animal Protection Campaign. This rescission was made because ACE believes strong, ethical leadership and a healthy work environment are critical components of an effective charity.
