Melania Trump's one-time friend Stephanie Winston Wolkoff opened up about the Trump family’s alleged grifts, and how it affected her friendship with the former US First Lady.

Wolkoff, who was also a “Trusted Advisor” to Melania, shared how the Trump Organization reserved several rooms at a hotel in Washington D.C. for former President Donald Trump’s inauguration in 2017, and refused to pay the bill. Instead of paying up, the organization passed the fees on to the Presidential Inauguration Committee (PIC), which is a non-profit organization, reported LGBTQ Nation.

Karl Racine, the attorney general for Washington D.C., has been investigating how the Trump family used the PIC to possibly host parties for personal reasons and enriched themselves before Trump’s presidential inauguration. The attorney general believes that the family misspent more than $1 million.

Referring to the hotel, Wolkoff told Daily Beast that the bill “should never have been sent to the PIC." Wolkoff, who is also the lead witness in Racine’s case, said, “That’s misuse of funding.” She added that Trump's company being involved in any way and making the PIC pay on their behalf, "doesn’t seem legitimate.”

She even tweeted the "proof" of how the Trump Organization was "directly involved with Trump's Presidential Inauguration Committee's $107 million."

As for her friendship with Melania, there was a fallout after Wolkoff reportedly felt that the Trump White House made her the scapegoat for the alleged misuse of funds at the 2017 inauguration. In 2020, Wolkoff even wrote a tell-all book, "Melania and Me: The Rise and Fall of My Friendship with the First Lady," in which she mentioned the inauguration.

Apart from Melania, her ties with other Trump family members were also cut off. On Thursday, she targeted Trump's daughter Ivanka in a tweet. Wolkoff wondered why Ivanka was receiving an "invitation" to give testimony to the committee that is investigating the Jan. 6 riot. She said that you "show up to testify," and it should not be an option.

She was reacting to a CNN report in which it said that the committee is asking Ivanka, who was a senior White House adviser back then, to voluntary cooperate with its investigation. The committee released a letter dated Thursday that was addressed to Ivanka seeking "voluntary cooperation with our investigation."

In the letter, the panel revealed new details about Trump’s actions in the days leading up to and on Jan. 6, 2021.

A spokesperson for Ivanka said Thursday that the former First Daughter "just learned that the Jan. 6 Committee issued a public letter asking her to appear." The spokesperson said that Ivanka did not speak at the rally held on Jan. 6. The spokesperson added that she publicly stated on Jan. 6 at 3. 15 pm that "'any security breach or disrespect to our law enforcement is unacceptable. The violence must stop immediately. Please be peaceful.'"
