This is political harassment and political extortion, and I'm glad to hear that this man (and the Koch brothers) are being investigated.
These are jim crow tactics being used on their employees. jim crow was not just about harassing Black people and trying to keep Black people from voting, it was also about harassing White people and making sure White people did nothing to assist or further the cause of Civil Rights or equality in this country.
These same Jim crow tactics were used against White people in the past, to force White people to go along with their racist agenda.
Whether a White person believed in racism or not, whether they wanted to discriminate against minorities or not, people with racist agendas made it virtually impossible for Whites that were not racist to not go along with it.
Many White people were facing losing their "friends", "family", their business, their jobs, and even their lives if they stood up for what was right or for equality or did not discriminate against Black people and other minorities. So, what this man (and the Koch brothers) are doing is using jim crow tactics to force their employees (the majority of whom are White, I'm sure), to go along with their political/racist/elitist agenda, whether they want to or not.
(Something we must also remember, is that Whites that helped in the Civil Rights movement and/or refused to discriminate, also did so at great risk).
