President-elect Joe Biden has selected Merrick Garland, a federal appeals court judge who in 2016 was snubbed by Republicans for a seat on the Supreme Court, as his attorney general, two people familiar with the selection process said Wednesday.

In picking Garland, Biden is turning to an experienced judge who held senior positions at the Justice Department decades ago, including as a supervisor of the prosecution of the 1995 Oklahoma City bombing. The pick will force Senate Republicans to contend with the nomination of someone they spurned four years ago — refusing even to hold hearings when a Supreme Court vacancy arose — but Biden is banking on Garland’s credentials and reputation for moderation to ensure confirmation.

Biden is expected to announce Garland’s appointment on Thursday, along with other senior leaders of the department, including former homeland security adviser Lisa Monaco as deputy attorney general and former Justice Department civil rights chief Vanita Gupta as associate attorney general, the No. 3 official. He will also name an assistant attorney general for civil rights, Kristen Clarke, the president of Lawyers’ Committee for Civil Rights Under Law, an advocacy group.

Garland was selected over other finalists including former Alabama Sen. Doug Jones and former Deputy Attorney General Sally Yates. The people familiar with the process spoke on condition of anonymity. One said Biden regards Garland as an attorney general who can restore integrity to the Justice Department and as someone who, having worked as both a federal prosecutor and a high-level supervisor inside the agency, will enjoy the respect of nonpartisan career staff.

Garland’s confirmation prospects were solidified as Democrats on Wednesday scored control of the Senate majority by winning both Georgia Senate seats.

Garland would confront immediate challenges if confirmed, including an ongoing criminal tax investigation into Biden’s son, Hunter, as well as calls from many Democrats to pursue inquiries into President Donald Trump after he leaves office. A special counsel investigation into the origins of the Russia probe also remains open, forcing a new attorney general to decide how to handle it and what to make public.

Garland would also inherit a Justice Department that has endured a tumultuous four years and abundant criticism from Democrats over what they see as the overpoliticization of law enforcement. The department is expected to dramatically change course under new leadership, including through a different approach to civil rights issues and national policing policies, especially after months of mass protests over the deaths of Black Americans at the hand of law enforcement.
