Boutique exercise chain owner takes heat after outing Ivanka Trump as one of her clients

The founder of a boutique fitness chain based in Washington D.C. drew criticism Thursday after she revealed Donald Trump’s daughter, Ivanka, used a pseudonym to sign up for one her classes, with some calling for a boycott of the chain.

“What you do when you find out Ivanka Trump just took [solidcore], but used an alias to sign up for class?” Anne Mahlum, founder of Solidcore, wrote on Facebook in a since-deleted post. “You reach out and ask for a meeting.”

Mahlum went on to say while she doesn’t know Trump, “I do know her father is threatening the rights of many of my beloved clients and coaches.”

Mahlum received a firestorm of criitcism from people who called her “biased and hypocritical” and accused her of violating her client’s privacy rights. Still, the fitness chain owner stood by her post.

"I am extremely proud of the inclusive community at [solidcore] that respects everyone's age, race, religion, sexual orientation, or otherwise, and it is my key priority to protect that community,” she wrote in a follow-up post. “As I said in my Facebook post, I do not know Ivanka, but I welcome the opportunity to open up the communication channels, and I hope she takes me up on my offer."
