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."

Biden’s nominee for secretary of the interior, Rep. Deb Haaland, D-Ariz., appeared before the Senate Energy and Natural Resources Committee for the first round of questioning in her confirmation hearing Tuesday.

Haaland introduced herself in the native language of the Laguna Pueblo and thanked her family, her partner and her ancestors. She also acknowledged that the hearing was taking place on the native lands of the Anacostia, Piscataway and Nakochtank tribes.

She said her priorities would be valuing career employees at the Department of the Interior and promoting clean energy. For Native American communities, she said she would focus on bringing broadband access to them and addressing the high number of missing and murdered Native American women. She also talked about her support for a modern Civilian Conservation Corps as a way of offsetting potential job loss from a transition to cleaner energy.

“But we must also recognize that the energy industry is innovating, and our climate challenge must be addressed," she said in her opening statement. "Together we can work to position our nation and all of its people for success in the future, and I am committed to working cooperatively with all stakeholders, and all of Congress, to strike the right balance going forward.”

Throughout the hearing, when questioned about her past statements and positions, Haaland said that if confirmed she would be advancing Biden’s interests. She dodged a question about her stance on fracking, saying the president does not support a fracking ban.

In his opening statement, Sen. John Barrasso, R-Wyo., said he was troubled by Haaland’s “radical” views, a sentiment also expressed by other Republicans on the committee. He said he would oppose Haaland’s nomination. During his questioning, Barrasso pressed Haaland on an October tweet that said Republicans don’t believe in science.

The committee will be back Wednesday at 10 a.m. for the second round of questioning.

The first hearing for Biden's pick to head the Department of Health and Human services, Xavier Becerra, ended Tuesday afternoon with little drama or contentious back-and-forths with Republicans despite their clear opposition to him on policy issues like abortion and health care.

Democratic senators highlighted Becerra's potential to make history as the first Latino to lead the department and his experience leading massive departments and in policy as a congressman for 24 years.

Only a handful of Republicans told Becerra to his face that they didn’t think he had the public health experience for the job, one of the key criticisms ahead of the hearing.

Senate Minority Leader Mitch McConnell sharply criticized him to reporters as the hearing was ongoing. But McConnell’s remarks were a reminder: Being cordial at a hearing doesn’t mean Republicans are going to vote for Becerra.

Becerra will head to the Senate Finance Committee Wednesday at 2 p.m, which will advance a vote on his confirmation to the Senate floor.

Rep. Trent Kelly, R-Miss., took to the House floor on Tuesday to speak in favor of his bill to name a Tupelo post office after U.S. Air Force Col. Carlyle “Smitty” Harris, a Vietnam prisoner of war who was held in the infamous "Hanoi Hilton."

The uncontroversial measure was slated to pass under the suspension of the House rules -- with debate expedited because it had the support of two-thirds of the chamber.

But in a surprise move, Rep. Sean Casten, D-Ill., blocked the measure, and instead forced the House to take a recorded vote on the bill Tuesday evening.

The reason? Kelly voted to overturn the election results on Jan. 6.

"As Representatives working every day on behalf of the American people, Rep. Casten believes that working with members regardless of political party is at the core of good public policy," Casten's chief of staff Cara Pavlock said in an email obtained by ABC News. "As a general matter, he does not suggest this action against members with whom we merely disagree, but that willingness to collaborate can only extend so far and to those that also hold the core value of upholding democracy."

"The vote to overturn the election results in the midst of a violent insurrection was a bridge too far," Pavlock wrote, adding that Casten also planned to vote against the post office renaming for that reason.

The bill did pass on a vote of 406-15.

The minor procedural dustup is one of many reminders of how Congress is still grappling with the aftermath of the Jan. 6 Capitol riot and that lawmakers are still coming to terms with how to approach colleagues who supported and amplified former President Donald Trump's efforts to undermine the results of the 2020 election.
