The man who ghostwrote Donald Trump's business memoir was expected to donate a portion of his royalties from the book's sales to an organization dedicated to defending and advancing the rights of low income immigrants.

The $55,000 gift to the National Immigration Law Center Justice Fund, announced Tuesday, is Tony Schwartz's latest effort to assuage his guilty conscience over Trump's presidential candidacy, something he says he feels partially responsible for.

Schwartz has opted for poetic justice, announcing in July that his share of the book's royalties would be donated to various charities that go against Trump's message that has included anti-immigrant rhetoric.

"The Art of the Deal" was first published in 1987 and spent more than 48 weeks on the New York Times bestseller list, selling more than a million copies. Schwartz received half of the book's $500,000 advance and half of all future royalties.

Schwartz has been vocal in his criticism of the Republican presidential nominee, tweeting about his disgust and telling the New Yorker, "I put lipstick on a pig. I feel a deep sense of remorse that I contributed to presenting Trump in a way that brought him wider attention and made him more appealing than he is." That's not likely to be erased from his conscious quickly but donating profits made off Trump to charitable causes might dampen the regret.

Trump threatened to sue Schwartz over his "defamatory statements" in the New Yorker.

Schwartz has donated additional royalties to Human Rights Watch, the Center for Victims of Torture, the National Immigration Forum and the Tahrirh Justice Center, according to McClatchy. In short, the places that clash most with Trump's campaign rhetoric have been the beneficiaries of his memoir's profits.

Schwartz was also expected to lead a press conference Tuesday — titled "From Hate to Healing, A Path Forward" — alongside leaders from minority communities to discuss how to move forward after this year's election.
