A congressional panel investigating Jeffrey Epstein's sex crimes released Monday a 2003 birthday letter that Donald Trump allegedly sent to Epstein – despite Trump's prior denials of its existence.

The letter, a typewritten message inserted into the sketched outline of a nude woman, was one of many notes sent by Epstein's friends that his associate Ghislaine Maxwell, now imprisoned, had compiled into a book for his 50th birthday.

The Wall Street Journal had reported on the existence of the book and letter in July, prompting a $10 billion defamation suit from Trump, 79.

The U.S. House Oversight Committee subpoenaed the book along with other documents from Epstein's estate, including bank records, as part of its probe launched this summer into the handling of the late sex offender's case.

Trump's alleged note consists of a short dialogue between "Donald" and "Jeffrey."
