Sen. Josh Hawley (R-Mo.) has been promoting his upcoming book about the tyranny of big tech companies, but a tweet he posted Thursday night made some wonder if he even knows what those companies are.

Thanks for making The Tyranny of Big Tech a best seller all week on Amazon ! You can get your copy here, Hawley tweeted, directing his followers to buy his book from one of the worlds biggest tech companies and thanking them for shopping there.

Along with Amazon, Twitter and the iPhone that Hawley used to tweet about his book are about as big tech as it gets.

In his book, Hawley, a staunch supporter of Donald Trump who promoted the ex-presidents attempts to overturn the 2020 election result, claims that big tech companies are a product of corporate liberalism. While many of the books ideas for reining in those companies have support from both parties, a Washington Post review of the book said the Missouri senators message is clouded by misfired attempts to tie the issue back to liberal movements.

Hawleys arguments about the dangers of cancel culture, another central theme of his book, have also fallen flat. On Thursday, CNN s Brianna Keiler dove into the irony of Hawleys claims hes been canceled or silenced when, in reality, he regularly appears on massive platforms and is on Fox News as often as you brush your teeth, she said.

Silenced, he says. But hes not and he knows it, Keilar concluded. Hes a smart man who sees opportunity in acting like a martyr.

Earlier in the week, Hawley accused the media of trying to silence him even while he was doing a live interview with The Washington Post about his book.
