Donald Trump made sexual comments about his daughter Ivanka to aides working in his administration, a former Department of Homeland Security official reportedly claims in an upcoming book.

Miles Taylor , a DHS chief of staff under Trump, described the alleged remarks from the former president as part of a wider pattern of sexism and inappropriate behavior toward women in his administration, according to Newsweek , which obtained an excerpt from the book.

Aides said he talked about Ivanka Trumps breasts, her backside, and what it might be like to have sex with her, remarks that once led John Kelly to remind the president that Ivanka was his daughter, Taylor wrote, recalling an alleged exchange with Kelly, who served as Trumps chief of staff between 2017 and 2019.

Afterward, Kelly retold that story to me in visible disgust. Trump, he said, was a very, very evil man.

Taylor said he also witnessed Trumps sexist behavior in meetings with Kirstjen Nielsen, who was secretary of homeland security from 2017 to 2019.

He said Trump would refer to Nielsen as sweetie and honey and critique the way she was dressed.

Representatives for Trump did not immediately respond to a request for comment.

Taylor left the Republican Party last year, saying the institution is poisoning Americans minds and going after the foundations of democracy itself.

He said in 2020 that he was voting for Joe Biden , publicly accusing Trump of trying to exploit the Department of Homeland Security for his own political purposes and to fuel his own agenda. He has also admitted to authoring an anonymous 2018 op-ed in The New York Times , where he claimed he was part of a group of staffers working against Trump from inside his own administration.

His book Blowback: A Warning to Save Democracy from the Next Trump is set for release on July 18.
