Tiara Mack, 28, entered the Rhode Island legislature in January 2021 - the first black openly gay woman to do so, and set tongues wagging with her July 4 video, which was filmed on one of her adopted home state's famed beaches.
The Democrat's video was shared with over 7,000 TikTok followers on her campaign account - @mackdistrict6 - and sparked a strong reaction, with 4,220 likes in the first 24 hours.
She caught the clip: "A promised senator thirst trap at Block Island."
Mack added a devil emoji, and joked: "How many nip slips am I allowed to get on the 4th of July?"

A friend off-camera replied: "You already have three."
Yet many were unimpressed with the action.
One social media user, Sherry Mann, tweeted: "Vote Tierra (sic) Mack, or what, she'll fall on them. How embarrassing to have anyone like this as a state senator. What kind of behavior is this to stick your (big) ass in the air and twerk. What's this kind of mentality, the kind I don't want in government. Seriously."

"I'm not a conservative and I'm disappointed," said another.
"Where do we draw the line on the behavior of public figures? I like when WE have a standard of decorum that we want OUR people to rise to. To be UNCOMMON to be admired! This ain't it."

Another announced: "We all need our representatives to be someone we are proud to support. Both parties. Deeply saddened that this woman is a senator in any state."
"If showing your ass was the message you intended, you succeeded. Parents take notes, is this something to aspire to."

Tucker Carlson, the Fox News host, was among those outraged by the clip.
He mockingly described her as "the next rising star of the Democrat party," and went on: "Why isn't she Secretary of State? Why aren't they pushing her for president?"

Mack herself then replied to some of the denunciations in her TikTok videos.
When one person commented that she "set the race back years with this," Mack replied: "This is tacky. This is lazy. What? No, baby girl - this ain't it."
