Former President Donald Trump again finds himself at odds with a once-loyal ally, and it is once more over a claim in a tell-all book that touches on the 2020 presidential election.

The book in question was written by former White House Counselor Kellyanne Conway, who insisted that she “may have been the first person Donald Trump trusted in his inner circle who told him that he had come up short this time” after his loss to now-President Joe Biden. Trump did not take the news kindly.

"Kellyanne Conway never told me that she thought we lost the election. If she had, I wouldn’t have dealt with her any longer — she would have been wrong — could go back to her crazy husband,” Trump posted on his social media platform, Truth Social.   

Her husband, George Conway, was a vocal critic of Trump during his wife’s time in his administration. He co-founded the anti-Trump Lincoln Project, an operation the former president is known to loathe.

In her memoir, "Here's The Deal," Conway wrote that she expressed her disapproval of her husband’s attacks on Trump. She said they “violated our marriage vows to love, honor, and cherish each other."

During and after his presidency, Trump has openly disparaged former aides who went on to write books that were critical of him or his conduct in the Oval Office. He has accused several former allies of concocting lies to tarnish his image or seeking to profit on their proximity to his orbit. 

The ex-president leveled this accusation against Conway by wondering aloud how "writing books can make people say some very strange things.”

For all of Trump’s vitriol on social media, Conway wrote in her book that her former boss actually encouraged her to write a book about her time in his White House in an endearing manner.

"Write a great book, honey. You made history. You were the first woman [to manage a winning presidential campaign]. You did a fantastic job. You should talk about it," Conway wrote, paraphrasing Trump in a meeting she had with him last year at Mar-a-Lago.
