Republican representative James Comer said the committee leading the probe will meet next week to hold former US president Bill Clinton in contempt.
Bill and Hillary Clinton have said they will refuse to testify in a Republican-led investigation into convicted sex offender Jeffrey Epstein.
« Every person has to decide when they have seen or had enough and are ready to fight for this country, its principles and its people, no matter the consequences », the Clintons wrote in a letter published on social media.
« For us, now is that time. »
The letter was addressed to Republican representative James Comer. He chairs the House of Representatives Oversight Committee, whose Epstein probe was slammed as « legally invalid » by the Clintons.
He said the committee will meet next week to hold former US president Bill Clinton in contempt, which could potentially lead to criminal charges. The Clintons said this was « literally designed to result in our imprisonment ».
