Biden's Day: President Biden delivers remarks on the Covid-19 pandemic at 4:15 ET. He will announce today that Merck & Co. will help produce Johnson & Johnson’s single-shot Covid-19 vaccine, according to administration officials. Vice President Kamala Harris will participate in the House Democratic Issues Conference tonight. 

Russia Sanctions: The Biden administration is imposing sanctions against Russia for actions against Russian opposition leader Alexei Navalny, who was detained by the Kremlin after surviving a near-fatal poisoning attack last year.

Supreme Court: The court will consider Arizona election rules, a case that sets the stage for the court to interpret a key Voting Rights Act provision. The court agreed Monday to consider reinstating a federal law denying disability benefits to residents of Puerto Rico.

Capitol Riot: FBI Director Christopher Wray appears before the Senate Intelligence Committee on the first of two days of hearings focused largely on the Jan. 6 Capitol riot.

💬Live Q&A: Join the lead authors of “The WSJ Tax Guide 2021,” Laura Saunders and Richard Rubin, with Personal Finance Editor Bourree Lam, at 3 p.m. ET as they answer questions about rules and changes related to remote work, stimulus payments and capital gains.

President Biden and Democratic allies on Monday worked to iron out the remaining disputes over the coronavirus relief package, which they hope to push through the Senate this week, despite left-wing frustrations over the exclusion of a minimum-wage increase, report Kristina Peterson and Andrew Duehren.

The administration will look to offer options for reunification inside the U.S. between parents and children separated under the Trump administration’s zero-tolerance policy on illegal immigration, Homeland Security Secretary Alejandro Mayorkas said Monday. The American Civil Liberties Union has identified about 5,500 such families, Tarini Parti and Michelle Hackman report.

• Some states plan to challenge the Biden administration’s rollback of work requirements for Medicaid recipients.

Republican Sen. Lisa Murkowski of Alaska held a meeting Monday with Neera Tanden, President Biden's pick to lead the Office of Management and Budget, but remained undecided whether to support the nomination.

Ms. Murkowki's decision could determine whether the leader of the Center for American Progress is confirmed to the OMB role. After Sen. Joe Manchin (D., W.Va.) said he would oppose Ms. Tanden’s nomination, Democrats in the 50-50 Senate have been working to find a Republican who will vote for her.

The White House is now focused on Ms. Murkowski and Sen. Kyrsten Sinema (D., Ariz.), neither of whom have said how they intend to vote, people involved in the discussions said. If Ms. Sinema joins Mr. Manchin in opposing her, Ms. Tanden would need a second Republican to cross party lines, an outcome that Senate aides said was unlikely.

"We had a sit-down meeting, which was good," Ms. Murkowski told reporters Monday, adding that she still had additional questions for Ms. Tanden.

President Biden is facing one of the most consequential early decisions he will make: whether to withdraw all U.S. troops from Afghanistan. In case you’re counting, Mr. Biden thus becomes the fourth president in a row to wrestle with this question. 

In Mr. Biden’s case, a campaign promise to end “forever wars” is colliding head-on with the stark reality that violence in Afghanistan has, in some ways, gone up, not down, since the Trump administration pledged exactly one year ago this week to withdraw all U.S. forces by this May.

The Biden administration said it will use “all available tools” to respond to alleged unfair trading practices by Beijing, releasing its first trade agenda Monday as required by Congress, reports Yuka Hayashi. The administration also described its “worker-centered” trade policy.

• It said it is committed to using tariffs and other tools to combat alleged unfair trade practices by China, including use of forced labor that targets Uyghurs and other ethnic minorities.
• Trade policy will feature “extensive engagement” with unions; past trade policies will be reviewed for their impact on workers, and labor obligations in existing trade agreements will be fully enforced, it said.

The Biden administration said it isn’t considering sharing its Covid-19 vaccine supply with Mexico, Tarini Parti and Juan Montes report. White House press secretary Jen Psaki said the next step for Mr. Biden would be economic recovery and the reopening of borders with neighboring countries once the pandemic has been managed.

• New U.S. cases and deaths were up Monday from a day earlier.
