The niece of Donald Trump smashed his argument that his signature was forged on a lewd message sent to celebrate pedophile Jeffrey Epstein's 50th birthday.

Tthe House Oversight Committee released the complete 238-page volume of a birthday book compiled by Ghislaine Maxwell Monday, reigniting a scandal that has had Trump's camp reeling for weeks.

The document contains a birthday note reportedly written by Trump, positioned near an illustration of a nude woman. The signature appears in a provocative manner, resembling pubic hair. Trump has vehemently denied involvement and has initiated a lawsuit against The Wall Street Journal for first publishing the story.

White House Press Secretary Karoline Leavitt attempted to dismiss the allegations Monday, stating emphatically that President Trump neither drew the picture nor signed it. However, her denial was quickly challenged by Trump's own niece.

Mary L. Trump, a psychologist and author known for her critical stance toward her uncle, weighed in on social media. "That's definitely his signature," she wrote on X. "Just saying."

The assessment of the daughter of Donald's older brother Fred Trump Jr. carries particular weight given her professional background and intimate family knowledge. She previously authored a scathing book about Trump titled "Too Much and Never Enough: How My Family Created the World's Most Dangerous Man."
