The first lady also criticized the media for reporting on "Melania & Me," a memoir of Wolkoff's time working on Donald Trump's January 2017 inauguration and in the East Wing.
"Once again, outlets chose to focus their coverage on pettiness over my positive work. There are plenty of opportunists out there who only care about themselves, and unfortunately seek to self-aggrandize by knowingly taking advantage of my goodwill," Melania wrote.
Wolkoff's book, the first to come from a former member of Melania's close group, described unflattering details of the first lady. Wolkoff also recorded conversations with Melania that she played for the media during her book tour.
Melania argued the conversations that Wolkoff played only had parts that were designed to make her look bad. In one citation, Melania is heard complaining "who gives a f*** about Christmas stuff" while talking about designing the holiday decorations for the White House.
She grilled Wolkoff as someone who "secretly recorded our phone calls, releasing portions from me that were out of context, then wrote a book of idle gossip trying to distort my character."
The piece, posted on the official White House website, marked the first time Melania Trump commented on the book and the tapes, which also revealed the first lady remarking about immigrant children being separated from their parents.
She did not mention Wolkoff by name but her meaning was clear. "Information that could be helpful to children is lost in the noise made by self-serving adults," Melania wrote. "I have most recently found this to be the case as major news outlets eagerly covered salacious claims made by a former contractor who advised my office. A person who said she “made me” even though she hardly knew me, and someone who clung to me after my husband won the Presidency."
"This is a woman who secretly recorded our phone calls, releasing portions from me that were out of context, then wrote a book of idle gossip trying to distort my character. Her 'memoir' included blaming me for her ailing health from an accident she had long ago, and for bad news coverage that she brought upon herself and others. Never once looking within at her own dishonest behavior and all in an attempt to be relevant. These kinds of people only care about their personal agenda- not about helping others," she added.
"To push forward a personal agenda that attempts to defame my office and the efforts of my team, only takes away from our work to help children," she resolved.
In the nearly 500 word post, Melania praised her Be Best work - which promotes well-being, online safety, and opioid abuse.
