Former US Secretary of State Hillary Clinton denied any connection to convicted sex offender Jeffrey Epstein during a six-hour hearing before members of the House Oversight Committee.

She has also criticized Republicans for the way they are handling the Epstein investigation.

Foreign media reports that during the closed-door hearing, she stated that she had never met Epstein and that she had no information about him or his associate and collaborator, Ghislaine Maxwell, NBC News reports.

"I had no idea about their criminal activities. I don't recall ever meeting Epstein. I never flew on his plane or visited his home or offices on the island," Clinton said.
