Presidential daughter Ivanka Trump is coming under a storm of criticism on social media for daring to defend the huge but controversial sales of a new book authored by elder brother, Donald Jr.

If anything, the pillorying Ivanka now endures seems to confirm the thesis of brother Don Jr.'s, new book, "Triggered: How the Left Thrives on Hate and Wants to Silence Us." The respected British newspaper, The Guardian, summed-up "Triggered" as “a high-pitched rant against American liberals who he accuses of turning the country into a socialist monument to political correctness." 

On Sunday, Ivanka tweeted: "A huge congratulations to my brother @donaldjtrumpjr on the publication of his new book, Triggered. Jared and I were honored to host a celebration of his success in D.C. this past week. Congratulations, Don, on #Triggering so many with a #1 NYT bestseller!"

Among the more subtle responses to Ivanka's tweet:

"Congrats on all the bulk purchasing of his book," said a commenter.

"I bought a box. Makes toilet paper great again, lol," wrote another.

"It doesn’t count when you have to reach #1 with bulk sales. He’s still the loser he’s always been," said another tweet.

Someone blamed Vladimir Putin for boosting Triggered's sales: "Putin @KremlinRussia_E nought [sic] 70,000 copies #trump crime family"

A tweeter more sympathetic to Ivanka wrote, "You look foolish promoting him."

And referring to the fact Don Jr. and his father actually had ghost writers pen their "best selling" books prompted this tweet: "Bulk buy for a book he didn’t actually write, just like dad!"

"Triggered" now sits atop The New York Times nonfiction bestseller list and has reportedly outsold the combined sales of the Number 2 and Number 3 top books on the list. Only problem is, the Times spoiled the book's otherwise notable bragging rights by appending a dagger (†) to the book's title.

The dagger indicates its belief a book made its way onto its  bestseller list in a way that seems “suspicious." In this case, most of "Triggered's" sales appear to come from suspicious bulk purchases and not individual sales.

“Institutional, special interest, group or bulk purchases, if and when they are included, are at the discretion of The New York Times Best-Seller List Desk editors based on standards for inclusion that encompass proprietary vetting and audit protocols, corroborative reporting and other statistical determinations. When included, such bulk purchases appear with a dagger (†)," explained the Times.

If books are being bought in bulk, this might mean people aren't reading them, which defeats the entire purpose of a bestseller list. Making it to the top of The New York Times list, however, inherently boosts sales because it makes people think everyone is reading the book.

The Republican National Committee (RNC) admitted it bought many copies of the book "to keep up with demand." Strangely, it denies buying the book in bulk.

It's still giving away copies of the book signed by Don Jr. to people donating to president Donald Trump's re-election campaign. 

The suggestion sales of his book are being artificially boosted is enraging Don Jr. He complained the Times placed a "deadly dagger" next to his book's name and claimed the newspaper does that "to a lot of conservative books" but without offering any proof to back-up this unfounded claim.
