The House Oversight Committee released a transcript from its first closed-door interview with former Attorney General Bill Barr in which he acknowledged the mishandling of the late sex offender Jeffrey Epstein’s detainment and pointed to other possible files.

Barr, who twice served as attorney general and led the Justice Department during President Donald Trump’s first term, was subpoenaed by Oversight Committee Chairman James Comer (R-KY) last month. His appearance marked the first interview in a sweeping inquiry that also sought sitdowns with former President Bill Clinton, former Attorney General Eric Holder, and former FBI Director James Comey.
