Business Insider says Heidi Cruz's daughter did not support her decision to leave Goldman Sachs.
Cruz left in 2015 to help her husband and Senator Ted Cruz with his presidential campaign.
Cruz says her daughter was only seven in 2015, but she still questioned Cruz's decision.
Cruz said her daughter asked her if being the First Lady of the US paid.
When she learned it's wasn't, she told her mother: "That's a bad deal for you."
