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.

One hundred and sixty chief executive officers sent an open letter to congressional leadership Wednesday, urging lawmakers to pass "immediate and large-scale federal legislation to address the health and economic crises brought on by the COVID-19 pandemic" on a bipartisan basis.

The letter asks Congress to "to authorize a stimulus and relief package along the lines of the Biden-Harris administration’s proposed American Rescue Plan," perhaps leaving some room for negotiation on what the final package will look like. But the letter makes clear that major business CEOs, including the heads of Morgan Stanley, Visa, United Airlines, BlackRock, Comcast and Google are pushing for relief on the scale of Biden's plan.

"The American Rescue Plan provides a framework for coordinated public-private efforts to overcome COVID-19 and to move forward with a new era of inclusive growth. The country’s business community is prepared to work with you to achieve these critical objectives," the letter says.

Just Tuesday, though, Sen. Mitt Romney, R-Utah, one of the few Senate Republicans who has shown willingness to buck his party, criticized the $1.9 trillion bill in a Wall Street Journal op-ed.

"The $1.9 trillion bill is a clunker. It would waste hundreds of billions of dollars, do nothing meaningful to get kids back to school, and enact policies that work against job creation. The Congressional Budget Office’s recent analysis of the plan found that more than a third of the proposed funding—$700 billion—wouldn’t be spent until 2022 or later, undermining the administration’s claim that the massive price tag is justified for urgent pandemic-related needs," Romney wrote.

Whether the pressure from big business will sway any Republicans in the Senate remains to be seen, but Wednesday morning's messaging from GOP lawmakers is pretty clear: They have no intentions of budging.
