She's his daughter, a product of him, and likely to continue to influence him and receive biased treatment in the future. Familial ties are much harder to break than business ones. Had she not been his daughter, firing alone may have been sufficient. However, one of her tweets even incriminates the whole family. "God already punished you for being black, so why would you make it worse by being gay. #shitpeopleinmyfamilysay!! Haha" They found themselves in hot water after posting about their allegiance with BLM, which has been a marketing bandwagon as of late. This leads to people digging into how sincere these businesses are, and finding a cache of noxious racist tweets by the director of a business, who is the CEO's daughter, is basically going to sound the death knell for a small business. Maybe before posting about your family's business' allegiance to a hot-button cause related to black people and racism, think about deleting all those racists tweets you made years ago talking about how black people should be eradicated, using the n* word with monkey emojis, and your posting of swastikas. Think about how this could impact the people around you, including your family, your customers, and other businesses who support you. I don't blame their landlord for wanting run away from any association with her toxic tweets, and likely there is a clause within their lease agreement allowing the breaking of the lease due to certain behavior.
