A white teen is getting a lot of praise online for calling out her mother after she was seen in a now-viral video hitting a Black cop.

The video caused outrage for several reasons. The Black woman, serving on the Metropolitan Police force, was working to contain a violent pro-Trump group the night before the terror attack on the Capitol Building

The woman, identified by her daughter as Therese Duke, hit Black officer, 28-year-old Ashanti Smith, in the face during the rally and was punched by Smith in response. The crowd of white men around them then felt comfortable attacking the police officer, physically dragging her before throwing her to another group of officers. It is unclear if any of the people who assaulted the officer have been charged.

But 18-year-old Helena Duke went viral herself for retweeting the video with a stinging barb. 

"Hi mom remember the time you told me I shouldn’t go to BLM protests bc they could get violent...this you?" she wrote on Twitter, adding on another tweet to prove that it was in fact her mom who hit the cop. 

The teen spoke to BuzzFeed News about the situation, telling them that her mom lied and said she was taking her aunt to get a procedure done. Instead, her mom, uncle and aunt went to a "Stop The Steal" rally in Washington, D.C.

"My initial reaction was more like, oh my gosh, I was right. I was actually right about them being there. It was very surreal because it was an insane video, first of all, and then it was the revelation that, oh, that’s my mother. That’s her," Helena told BuzzFeed News, adding that the video was sent to her by her cousin. 

"Before President Trump was elected, she was a Democrat for the majority of her life. And then, I don't know what happened. Something switched in her brain, and she went through a very dramatic change to very far right. I obviously feel very sad that they have to go through it, too, but that I'm not alone, and that they’re not alone," she added, referencing other kids who either contacted her or took to Twitter after noticing their parents at any of the violent Trump rallies that took place last week. 

BuzzFeed News reported that over the past few years, it has become common for white people to grow distant from family members who are now obsessed with President Donald Trump and adhere to conspiracy theories like QAnon.

The situation has gotten even more dire for those who noticed family members participating in the attempted coup on Congress last Wednesday. 

Helena's tweet now has more than 400,000 likes and her mother has demanded she remove the tweet. 

"We are not proud of how things went in DC. I know you are upset but putting us in danger isn't going to solve anything. Please...I am Begging you to remove," her aunt told her in texts seen by BuzzFeed News. 

Helena said she was thrown out of her mother's home when she participated in the protests against racial injustice and police brutality last summer, telling BuzzFeed that her mother made many bigoted statements about Black Lives Matter

"She told me she thought Black Lives Matter was a violent organization and they would be inciting violence. I always felt almost heartbroken over how they viewed the world and how skewed it was and how they wouldn't allow me to express my views," Helena said.

"But showing that they can act in such a horrible way is just really appalling to me. I am honestly very disappointed to have to be part of this family that is so...just, very not welcoming or supportive. I don’t feel safe being part of this family."
