A US panel investigating the crimes of Jeffrey Epstein has requested that the executors of his estate produce a number of documents, including a book said to have contained personal messages for his 50th birthday.
The subpoena from James Comer, the leader of the House Oversight Committee, represents an expansion of his investigation into Epstein, the disgraced late paedophile financier.
Last month, the Wall Street Journal reported that the birthday book his associate Ghislaine Maxwell created in 2003 contained submissions from various Epstein acquaintances, including a bawdy note allegedly bearing the name of Donald Trump, who was then his friend.
Trump has denied writing any such letter.
The president said the alleged note was "fake" and began defamation proceedings against the Journal's parent company and its owner, Rupert Murdoch. The company, Dow Jones, stood by its reporting and vowed to fight the legal case.
