Ivanka Trump has blasted a performance art piece that features a lookalike of her vacuuming up crumbs that spectators toss at her.
"Women can choose to knock each other down or build each other up," the first daughter tweeted on Tuesday, alongside a link to a story on the exhibit. "I choose the latter."
The piece by New York-based artist Jennifer Rubell, titled "Ivanka Vacuuming", invites visitors at the Flashpoint Gallery in Washington, DC, to "throw crumbs on the carpet, watching as Ivanka elegantly vacuums up the mess, her smile never wavering."
A pink-clad model in three-inch heels plays an ersatz Ivanka making the mess disappear over and over again, the New York Post reported. The work, presented by the CulturalDC arts organisation, has been opened to the public since February 1, from 6 p.m. to 8 p.m.
A description of the work calls Trump a "contemporary feminine icon".
"(She is) a figure whose public persona incorporates an almost comically wide range of feminine identities -- daughter, wife, mother, sister, model, working woman, blonde."
The gallery text also calls the act of throwing bread crumbs for her to vacuum "surprisingly pleasurable".
Her brothers also slammed the work.
"Sad, but not surprising to watch self professed 'feminists' launching sexist attacks against Ivanka. In their crazed world, sexism is OK if hurts their political enemies," Donald Trump Jr. tweeted.
Added Eric Trump on Fox News: Ivanka is a "powerful woman who has done more for women than probably anybody in Washington, DC".
