Samaria Rice, the mother of 12-year-old Tamir Rice who was gunned down by police in 2014, issued a scathing response to Shaun King after the activist publicized details of a recent conversation they had.

King published a record of a conversation he had with Samaria on Tuesday for his blog, "The North Star with Shaun King." In the post, he highlighted the fundraising he did for Samaria in the wake of her son's death. Samaria questioned King's motives in her response before adding that she never gave him permission to raise money for her family.

Samaria also referenced previous reports that accused King of embezzling thousands of dollars by exploiting the death of Tamir Rice when $60,000 in donations couldn't be accounted for.

"Why do you think it's so important to tell folks we had a conversation?" she asked in her Instagram post. "Well we talked and everything that was said was very toxic and uncomfortable for me to hear that you raised additional money and then say you did not want to bother me. Personally, I don't understand how you sleep at night. I never gave you permission to raise nothing. Along with the United States, you robbed me for the death of my son."

She continued by calling King an imposter and questioned his race.

"You gave me a cop and donut conversation. All lies Shaun, please stop thinking we on the same page," Samaria said. "As a white man acting black, you are [an] imposter that can not be trusted. My son was 12 years old, and DOJ needs to reopen his case period. Tamir Human rights was violated, why would you so ever make it about you? You are a selfish self centered person and God will deal with you White man."

Shaun King's post has since been taken down.
