Former FBI Director James Comey plans to speak to Amazon employees on Monday at 10 a.m. in Seattle as part of his ongoing book tour, sources with knowledge of the event told The Intercept.

Comey’s book, “A Higher Loyalty,” has already drawn the furious attention of President Donald Trump, who has simultaneously been battling on Twitter with Amazon, its CEO Jeff Bezos, and Bezos’s newspaper, the Washington Post.

Trump has repeatedly slammed Amazon for unfair competition by skirting state sales tax laws and has accused the company of milking the U.S. Postal Service. He regularly refers to the Post as the “Amazon Washington Post.”

Amazon does not own the Washington Post, Bezos does, but Trump does not draw that distinction.

Comey is speaking at a semi-regular event at the Amazon headquarters known as a “fishbowl.” A spokesperson for Amazon wasn’t immediately available to comment.

Comey’s decision to take his book tour directly to Amazon only promises to heighten the tensions.
