"What I did was not okay, and I'm so sorry," Claudia Oshry said in a tearful Instagram video

The tech platform Oath has canceled a popular show starring Claudia Oshry (of @girlwithnojob Instagram fame, boasting 2.8 million followers) and her sister Jackie amid controversy over their conservative commentator and anti-Islam activist mother Pamela Geller — and past racist tweets of their own.

“The Morning Breath, an Oath social media show, is being cancelled immediately,” a spokesperson for Oath tells PEOPLE in a statement. “We have launched an internal investigation and will take other appropriate steps based on the results of the investigation.”

Both Claudia and Jackie — who runs her own popular Instagram account, @jackieoproblems — have issued apologies on social media.

“Hi guys. Obviously need to address a lot of what happened today, but first and foremost, I just need to apologize,” Claudia, 23, said in a tearful video posted Wednesday. “Some news broke this morning about who my mom is, and then some really disgusting, vile, stupid tweets of mine resurfaced. I need to just come right out and say how sorry I am. It’s not cool, it’s not funny.”

“I was a dumb kid, I was 16, I thought I was being funny and cool on Twitter, and it’s not,” she continued. “I’m not racist. I can’t believe I even have to say that. But I’m so sorry to anyone who read those tweets and had a reaction and was upset, because you’re totally entitled to that reaction, but it’s so important for you guys to know that that’s not who I am. And if you guys me the opportunity to show you who I am and what I stand for, I would be so grateful. But I understand that these things take time, and what I did was not okay, and I’m so sorry.”

Jackie, 25, posted a screenshot of a written note apology.

“I want to express my utmost, sincere apologies for the indefensible comments that I’ve said in the past,” reads the note. “That is not a reflection of who I am as a person today and I am truly sorry to everyone I’ve offended and let down. All I can do now is reflect and learn from this experience by showing everyone the good that is in my heart.”

The controversy arose Wednesday after The Daily Beast published an article outing the fact that the social media stars (and their two other Instagram-famous sisters, Margo and Olivia) are the daughters of Geller, a right-wing activist who has been denounced for hate speech.

Following the news, past tweets of Claudia and Jackie’s featuring anti-Muslim sentiments began circulating online.

In a statement provided to The Daily Beast after the story’s publication, Claudia said she and her siblings don’t align with their mother’s ideologies.
