Pearl Love, who is a social worker, said she was commuting to her office on April 28 when a woman began berating her with racist and transphobic language. When the woman didn't relent, Love took out her cell phone and began recording the encounter, ABC News reports.
The clip, which can be seen below, has been viewed over 240,000 times since Love uploaded it to Facebook on Monday.
At one point, the woman is heard blasting Love for "living in a man's penis and body with women's makeup on," and eventually, appears to slap the phone out of Love's hand, at which point the video cuts off.
Love, who moved to the United States from Taiwan in 1998, told Gawker she posted the video because "if I can show people that this is what I face everyday, that would be a good thing."
Still, she couldn't have expected to receive a personal note from Clinton herself. Commenting on Love's video, the Democratic presidential hopeful wrote, "Pearl, I'm so sorry you experienced this. This all-too-high prevalence of violence and hatred faced by the transgender community -- today, in 2016! -- is a rebuke to all of us."
Jason Tengco, Clinton's Asian-American Pacific Islander (AAPI) Outreach Director, shared a screenshot of the post, which can be viewed below.
Clinton was introduced to Love when the candidate visited New York's LGBT Center on the campaign trail in April, DNA Info reports.
Later, on May 5, Love wrote on Facebook that she felt "amazing" after reading Clinton's response to the attack.
"I feel loved, my dear friends, thanks for all support," Love wrote.
The Huffington Post reached out to Love for additional comment but hadn't heard back by time of publication.
