Andrew Mountbatten-Windsor is facing growing pressure from US officials and the family of his prominent accuser Virginia Giuffre to testify in the US about his links to paedophile financier Jeffrey Epstein.
Speaking to the BBC, Democrat Congressman Ro Khanna said the Royal Family had not been transparent, while Democrat Congresswoman Teresa Leger Fernandez said King Charles III should direct his brother to go to the US to answer questions.
Earlier on Tuesday, the King said the Royal Family were ready to support police in their inquiries.
Andrew has repeatedly denied any wrongdoing and reached an out-of-court settlement with Giuffre in 2022 containing no admission of liability.
In the King's first intervention in the latest round of revelations in the Epstein scandal, a spokesperson for Buckingham Palace stated if they were approached by the police, they stood ready to support them in their investigation.
The spokesperson added the King had made clear...his profound concern over allegations against his brother, and the King and Queen's thoughts and sympathies have been, and remain with, the victims of any and all forms of abuse.
Thames Valley Police announced on Tuesday it was assessing a complaint by anti-monarchy group Republic over the alleged sharing of confidential material by Andrew with Epstein.
The former prince appears to have knowingly shared confidential information with Epstein from his official work as trade envoy in 2010 and 2011, according to material in the latest release of files seen by the BBC.
Andrew has been contacted for comment but is yet to respond.
When asked by the BBC if the former prince should go to the US, Khanna said that would be appropriate.
The Congressman, who co-sponsored the law that compelled the justice department to release the Epstein files last year, also said the Royal Family should come clean and lay out what they knew and what action they're going to take.
Khanna emphasized they should also consider compensating survivors for the horrors that took place, given their wealth.
In a statement a day prior, Khanna labeled this the most vulnerable period for the British monarchy and asserted that stripping Andrew of a title was insufficient.
He stated, The King has to answer what he knew regarding allegations connected to Epstein.
As the scrutiny intensifies, Andrew has relocated from his Windsor home to Wood Farm on the Sandringham Estate while renovations are conducted on his new permanent residence.
Congresswoman Teresa Leger Fernandez, part of the House Oversight Committee, has amplified calls for transparency from Andrew, asserting to the BBC's Newsnight that he should reveal details of his connections and activities.
Moreover, Sky Roberts, brother of Virginia Giuffre, has pressed for Andrew to appear before Congress and address allegations directly.
Recent correspondence from the US Department of Justice indicates multiple failed requests for Andrew’s cooperation in Epstein inquiries, creating considerable frustration among authorities.
The former prince cannot be compelled by a subpoena to appear in the US, further complicating matters as Andrew faces mounting pressure in light of new documents released related to Epstein.
The claims surrounding Andrew include newly surfaced photographs and witness statements suggesting troubling interactions he had in connection with Epstein.
Andrew continues to deny any wrongdoing, asserting that mention in Epstein files alone is not indicative of misconduct.
