Months after being marred over the handling of cases against President Donald Trump’s allies, the federal prosecutor’s office in Washington has returned to the spotlight as it mounts an expansive investigation and begins to bring criminal charges connected to the deadly insurrection at the U.S. Capitol, raising the stakes for President-elect Joe Biden’s pick to lead the largest U.S. attorney’s office in the country.

As Biden begins to fill top roles at the Justice Department, several former career prosecutors are said to be interested in returning to lead an office that saw its ranks demoralized last year as then-Attorney General William Barr intervened in criminal cases to the benefit of Trump’s political allies.
