Arizona Democrat Adelita Grijalva was sworn in to the House Wednesday after a record 50-day wait, vowing to immediately join an effort to disclose files related to the late sex offender Jeffrey Epstein. Grijalva had expressed no special interest in the Epstein case prior to her Sept. 23 election. But she became intertwined in the fate of a bipartisan effort to disclose Justice Department files related to the disgraced financier after it became clear she could provide the final necessary signature on a discharge petition forcing a House vote on the matter.
