Federal prosecutors in the Biden Justice Department worked closely with abortion-rights groups to track anti-abortion activists while withholding key evidence in FACE Act prosecutions, according to a 900-page report released by the DOJ on Tuesday detailing evidence of political bias under the Biden administration.

The report, the first of several to be released by the Trump administration’s Weaponization Working Group, is based on a review of roughly 700,000 internal records and represents the most detailed account to date of how the Freedom of Access to Clinic Entrances Act was enforced in the years following the Supreme Court’s 2022 Dobbs v. Jackson Women’s Health Organization decision.
