On Tuesday, Shalanda Young is appearing before the Senate Budget Committee on her nomination as deputy director of the Office of Management and Budget (OMB). Young's appearance comes as criticism over Neera Tanden's nomination for Office of Management and Budget director has led some senators to push for Young to head the office.

Sen. Richard Shelby, R-Ala., the top Republican on the Appropriations Committee, threw his weight behind Young as an alternative to Tanden last week as Tanden's nomination has become jeopardized by her past tweets critical of Republicans.

"I believe she would be good in that role. She’s smart, she knows the process inside-out, and she’s an honest broker who has demonstrated the ability to work with both sides and get things done. She would have my support, and I suspect many of my Republican colleagues would support her, as well," Shelby said in a statement. "But that’s up to the Biden Administration.”

Tanden has had votes in the Budget Committee and the Homeland Security and Governmental Affairs Committee postponed as the White House works to secure votes necessary for her confirmation. Tanden met on Monday with Sen. Lisa Murkowski, R-Alaska, who said that even after the meeting she is still undecided about how she'll vote on Tanden's confirmation. The White House has maintained support for Tanden.

The Biden administration is sanctioning seven Russian officials and is adding one government research institute and 13 businesses to its export restrictions, senior administration officials announced this morning.

These sanctions are the first U.S. penalties over the poisoning of Russian opposition leader Alexei Navalny's poisoning last August after former President Donald Trump's administration declined to act, even though a senior official said today the U.S. intelligence community "assesses with high confidence that officers of Russia's Federal Security Service, FSB, used a nerve agent known as Novichok to poison Russian opposition leader Alexei Navalny on August 20, 2020."

Because of Trump's inaction, a second official said the U.S. was "in many ways catching up to the EU and the U.K.," both of which sanctioned six individuals and one entity in October. Coordinating with those key U.S. allies makes these sanctions "stronger and more effective, particularly when it comes to Russia," the first official said, because Europe has closer business ties.

But these sanctions have been cast as falling short, particularly after Navalny's supporters circulated a list of Russian officials they called on the West to sanction. But it could be because the U.S. doesn't want to make a domestic political issue in Russia a further drag on relations. Biden is "neither seeking to reset our relations with Russia, nor are we seeking to escalate" with Russia, the first senior official said.

"Our goal is to have a relationship with Russia that is predictable and stable. Where there are opportunities for it to be constructive and it is in our interest to do so, we intend to pursue them," they added. That includes a possible dialogue on "strategic stability," especially nuclear arms control.

President Joe Biden is expected to announce a major partnership Tuesday afternoon between pharmaceutical giants Merck & Co. and Johnson & Johnson to help produce J&J's single-shot vaccine, a White House official confirms to ABC News. The move, first reported by the Washington Post, will help increase vaccine supply of the single-shot vaccine.

The FDA approved an Emergency Use Authorization for the vaccine Saturday, which triggered the shipment of nearly 3.9 million doses of the vaccine. Of those, 800,000 are expected to go directly to pharmacies.
