Biden issued a major disaster declaration for Oklahoma in the wake of winter storms in the U.S. south. The declaration covers 16 counties in Oklahoma and allows increased federal funding for recovery.

On Saturday, Biden issued a major disaster declaration for Texas, which freed up funds to aid recovery efforts after the storms left millions without power. The president is set to visit Texas on Friday to see relief efforts and visit a vaccine distribution facility.

The Republican Party is both less divided and more divided than it seems at the moment -- and not in ways that glide along the easiest political paths.

On the question of former President Donald Trump, the GOP is less divided than a colorful House leadership news conference might make it seem. The party still belongs primarily to Trump, as the CPAC gathering that begins Thursday in Florida will demonstrate.

On the question of President Joe Biden's agenda, there's actually more GOP dissension than meets the eye. The first floor votes on Biden's COVID-19 package are coming Friday in the House, yet united Republican opposition in Congress doesn't align with public polling on the topic.

Among the public at large, Biden and his COVID plans are considerably more popular than Trump and opposing COVID relief, at least for now. But Republican lawmakers appear to fear more political blowback in opposing Trump than voting "no" on COVID bills.

Tom Vilsack was sworn in as the secretary of agriculture Wednesday evening in a ceremony the vice president said was her first via Zoom.

Harris was in the Eisenhower Executive Office Building with a pool of journalists and Vilsack appeared on a large screen with his family.

"Congratulations, Mr. Secretary and to the whole family," Harris said after he was sworn in. "The president is so excited. We've got a lot of work to do and we'll do it together."

Vilsack is returning to a role he held in the Obama administration for eight years. He previously served two terms as Iowa's governor.

He was confirmed on Tuesday by a vote of 92-7.

Biden has reversed former President Donald Trump's presidential proclamation restricting immigration during the COVID-19 pandemic citing the economy, saying it does not advance the interests of the United States.

"To the contrary, it harms the United States, including by preventing certain family members of United States citizens and lawful permanent residents from joining their families here. It also harms industries in the United States that utilize talent from around the world. And it harms individuals who were selected to receive the opportunity to apply for, and those who have likewise received, immigrant visas through the Fiscal Year 2020 Diversity Visa Lottery," Biden wrote in a proclamation of his own.

The first day of hearings for Biden's pick for secretary of health and human services, Xavier Becerra, kicked off with glowing praise from Democrats, who heralded his experience, and criticism from Republicans, who think his resume is a detractor.

Both Sen. Patty Murray, D-Wash., and Sen. Diane Feinstein, D-Calif., who introduced Becerra, highlighted his 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. But Sen. Richard Burr, R-N.C., said he is “not sold” Becerra has the “necessary experience or skills to do this job at this moment.”

Becerra, in his opening statement, said he was committed to working in a bipartisan way.

“No one understands your states and communities better than you. We may not always agree, but if I’m fortunate enough to be confirmed, I will always listen to you and keep an open mind, find common cause, and work with you to improve the health and dignity of the American people,” Becerra said.

Becerra laid out his "vision" for the department with three goals: make COVID-19 treatments more accessible, bring down the cost of health care and restore faith in public institutions by putting science first.
