A prominent lawyer who has represented hundreds of Jeffrey Epstein's victims is calling on Congress to subpoena the disgraced financier's estate for a copy of an alleged birthday book that the Wall Street Journal reported contains a "bawdy" letter from Donald Trump.

       Attorney Brad Edwards claimed in an interview on MSNBC's "The Last Word with Lawrence O'Donnell" on Wednesday that some of his clients were involved in assembling the book and could attest to its authenticity.

       "If anyone cares for a solution as opposed to perpetuating scandal, there is an obvious and easy way to obtain the book at the center of the latest controversy. It's Jeffrey Epstein's 50th birthday book, and like all other similar possessions, the estate is obviously in possession of it," Edwards said in a statement to ABC News. "Ask or subpoena the estate or their lawyers, and everyone will then have the book and can move on, which is best for the victims."

       According to a report in the Wall Street Journal, Trump allegedly sent Epstein a letter in 2003 for his 50th birthday, which was included in a book made for Epstein that contained letters from numerous Epstein associates.

       Trump has denied the existence of the letter and filed a $10 billion defamation lawsuit against the Wall Street Journal. ABC News has not been able to confirm the existence of the letter.

       "We have full confidence in the rigor and accuracy of our reporting, and will vigorously defend against any lawsuit," a spokesperson for Wall Street Journal owner Dow Jones said in a statement.

       An attorney for the Epstein estate, when asked about Edward's remarks, said they "will comply with all lawful process." The representative did not respond to questions about whether the estate has the book or if it contains a letter from Trump.

       Edwards argued that releasing the book would resolve any questions about the letters included in it while respecting the victims of Epstein, the wealthy financier and convicted sex offender who died by suicide in jail in 2019.

       "The existence of the book is an absolute fact. Now, who wrote letters? What's in the book? You're going to have to get the book to figure it out," Edwards said on MSNBC. "But this isn't something that needs to be a mystery forever and drag the victims into all kinds of anxiety for nothing."

       Neither the White House or the Justice Department immediately responded to a request for comment from ABC News.
