Merrick Garland, Biden's pick for attorney general, could face tricky political questions during his confirmation hearing before the Senate Judiciary Committee today. In the wake of the Jan. 6 attack on the Capitol, Garland and Democrats are expected to point to Garland's work prosecuting the Oklahoma City bombing as evidence of his ability to investigate and prosecute domestic terrorism.

"If confirmed, I will supervise the prosecution of white supremacists and others who stormed the Capitol on January 6 – a heinous attack that sought to disrupt a cornerstone of our democracy: the peaceful transfer of power to a newly elected government,” Garland will say.

Garland's opening statement also conveys a commitment to equity, saying that upholding the Civil Rights Act remains "urgent" for the Department of Justice. Garland has received ample bipartisan support, ahead of his confirmation hearings before Senate Judiciary Monday and Tuesday, 61 former federal judges and a bipartisan group of more than 150 former Justice Department officials have penned letters in support of Garland's confirmation.

Biden and domestic policy adviser Susan Rice met virtually with Black essential workers on Tuesday, including health care workers, child care workers and others from across the country to thank them for their work throughout the COVID-19 pandemic.

"You are heroes and your service, we honor. A disproportionate number of Black Americans serve as front-line workers and as first responders, putting yourselves at greater risk of contracting COVID-19," Rice said. "And one in four deaths from COVID-19 have been those of Black Americans, and so during this Black history month, we wanted to say thank you, to lift up your voices, and your service and your needs."

Biden listened to the participants and asked questions. He also touted his administration's COVID-19 relief bill, talking about how it would help industries and individuals. Biden said his administration is focusing on the needs "particularly of the most left behind community, the African American community."
