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 toured the Harris County Emergency Operations Center in Houston as the first first stop on his trip in Texas in the wake of deadly winter storms. He was joined by Sen. John Cornyn, R-Texas, and other lawmakers and local officials.

"It’s a hell of an operation you’ve got here," Biden said upon arriving to the center.

The director of the center, Mark Sloan, detailed the operations of the facility and of the impact of the winter storms on the region. He said that of the 5 million residents in the county, the storm left 1.5 million people without power and heat and detailed the county's trouble getting water to residents, noting that approximately 3.5 million were without water. He talked about the emergency response, including handing out meals and water.

Biden thanked the workers, saying they were saving lives and "doing God's work."
