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.

Senate Majority Leader Chuck Schumer, in a remarkably candid moment, told reporters that during a closed-door lunch with his caucus Tuesday, he made a strong pitch for them to set aside differences over specific policies like the minimum wage hike and just vote for the president's COVID-19 relief bill.

Sen. Dick Durbin, D-Ill., then went a bit further after Schumer left the room and said the majority leader had "begged" his members to drop their opposition, emphasizing that the relief bill is Biden's signature legislation, and they need to stick together.

"He's begging all of us -- despite disagreements people may have -- this is the Administration's signature bill...And we need to stick together," Durbin recounted.

Some moderate Democrats like Sens. Joe Manchin, D-W.V., and Kyrsten Sinema, D-Ariz., have expressed concern about a $15 per hour minimum wage hike included in $1.9 trillion relief proposal. Manchin said an $11 an hour increase would be more appropriate for his state.

Republicans have hammered Democrats for forcing the increase on businesses suffering under the economic strains of the pandemic, but supporters of the wage increase -- a doubling of the current federal minimum wage -- note that the Biden plan is implemented over a five-year period.

GOP Sens. Tom Cotton of Arkansas and Utah's Mitt Romney introduced a plan Tuesday that would increase the minimum wage to $10 per hour by 2025 with a mandatory requirement that businesses implement E-Verify to ensure undocumented workers do not receive the increase.

The GOP proposal is not expected to be adopted as Democrats speed toward passage of the overall Biden plan.
