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.

After an expanded detention facility for child migrants reopened in Carrizo Springs, Texas, Rep. Alexandria Ocasio-Cortez, D-N.Y., tweeted Tuesday, “This is not okay, never has been okay, never will be okay - no matter the administration or party.”

In a press briefing Wednesday, Psaki attempted to cast the Biden administration’s efforts to manage immigration as a major improvement over President Donald Trump’s policies but didn’t fully address Ocasio-Cortez's criticism that such facilities shouldn’t exist at all.

Psaki said the administration had three options when it comes to child migrants: to send them back to their countries (which she said can be dangerous), to transfer them to a facility managed by the Department of Health and Human Services, or to put them in the care of families or sponsors "without any vetting." She said the administration has chosen the middle option.

“What we are doing is working as quickly as possible to process these kids into these HHS facilities, which have been revamped, which have medical and educational services available, so that we can then transfer them to families. That's what our approach is,” Psaki said.

Psaki would not commit to a request to allow media in to prove that children are treated humanely, citing privacy and security concerns. Psaki tried to explain the administration’s options in dealing with minors at the border and why the detention facilities have become a primary strategy.

“This is a difficult situation. It's a difficult choice. That's the choice we've made,” she said.

Psaki also attempted to defend delays in transferring children from facilities run by Customs and Border Protection, which often lack amenities, to Health and Human Service facilities that are intended for longer-term care. By law, children are supposed to spend no more than 72 hours in Customs and Border Protection facilities after initial apprehension.

“There were some delays last week because of weather, and because some of these facilities to safely move these kids to, did not have power and were not in a place where they could -- they had the capacity to take in these kids and do it safely. That is not our objective. That is not our goal," Psaki said. "So some, unfortunately, did stay four days, five days, or longer, but the objective is to move them as quickly as possible to the HHS sponsored facilities.”
