In 2014, Koch Industries Inc. and the Charles Koch Foundation granted $25 million to the United Negro College Fund (UNCF). In protest of the Kochs, the American Federation of State, County and Municipal Employees, a major labor union, ended its annual $50,000–$60,000 support for the UNCF, saying that the UNCF's involvement with the Charles Koch Foundation was 'a betrayal of everything the UNCF stands for' because, they said, the Koch brothers were 'the single most prominent funders of efforts to prevent African-Americans from voting'.
