Mulroney, whose children served as bridesmaids and groomsmen at Prince Harryand Meghan's wedding, later said in a since-deleted comment, "@sashaexeter, you are right when you say 'this s--t needs to stop'. As leaders, we need to join hands and call out wrongs. I know we have different experiences. And that is something that, even in the course of a heated argument, I need to acknowledge and understand. I am unequivocally sorry for not doing that with you, and for any hurt I caused. As I told you privately, I have lived a very public and personal experience with my closest friend where race was front and centre. It was deeply educational. I learned a lot from that. I promise to continue to learn and listen on how I can use my privilege to elevate and support Black voices."

However, not long after sharing this public apology, Mulroney allegedly sent another message threatening Exeter with a "liable suit," likely intending to write "libel". Exeter posted a screenshot of this to her Instagram Stories.

Exeter said she is now taking a break from social media as well, but felt it was important to speak out in the hopes that it will "help change things for the next generation," including her daughter Maxwell She wrote, "I will be dammed if my child ever has to deal with this level of ignorance."
