Ashley Biden’s Diary Was Shown at Trump Fund-Raiser. Weeks Later, Project Veritas Called Her.

In July 2020, a single mother of two moved into the rented home of a former boyfriend in Delray Beach, Fla. The woman, Aimee Harris, a Trump supporter, told the former boyfriend that she had little money, had nowhere to live and was in a bitter custody dispute. Shortly after moving into the rental, Ms. Harris learned that Ms. Biden — also a friend of the former boyfriend — had been staying at the home earlier that year during the pandemic.

Ms. Biden had moved back to the Philadelphia area in June 2020, around the time her father clinched the Democratic Party’s nomination for president. She stored a couple of bags of her belongings at the rental house along with her diary, and she told her friend, who was leasing the home, that she planned to return to retrieve her things in the fall.

In August, Ms. Harris reached out to Robert Kurlander, a friend who had been sentenced to 40 months in prison in the 1990s on a federal fraud charge and had expressed anti-Biden sentiments online, to say she had found the diary. The two believed they could sell it, allowing Ms. Harris to help pay for the lawyers representing her in the custody dispute.

New details from interviews and documents have further fleshed out what happened next. Mr. Kurlander contacted Elizabeth Fago, the Trump donor who would host the fund-raiser attended by Donald Trump Jr. When first told of the diary, Ms. Fago said she thought it would help Mr. Trump’s chances of winning the election, according to two people familiar with the matter.

Richard G. Lubin, a lawyer for Ms. Fago, declined to comment.

On Sept. 3, Ms. Fago’s daughter alerted Project Veritas about the diary through its tip line.

Three days later, Ms. Harris and Mr. Kurlander — with the diary in hand — attended the fund-raiser attended by Donald Trump Jr. at Ms. Fago’s house in Jupiter, Fla., to see whether the president’s re-election campaign might be interested in it. While there, Mr. Kurlander showed others the diary. It is unclear who saw it.
