White House COVID-19 response team holds briefing
The White House COVID-19 response team at a virtual press briefing Monday acknowledged coronavirus variants "remain a great concern," but overall stressed Americans should take a vaccine as soon as it becomes available, pushing back on any concerns over getting a vaccine now despite variants evolving.
"When the vaccine becomes available to you, please get vaccinated," said Dr. Anthony Fauci, Biden's chief medical adviser on COVID-19.
Fauci said vaccinations are the best way to fight mutations because they prevent the virus from spreading and replicating.
"There is a fact that permeates virology, and that is: Viruses cannot mutate if they don't replicate," Fauci said.
He and Centers for Disease Control and Prevention Director Dr. Rochelle Walensky also stressed wearing a mask and social distancing -- hours ahead of Biden's transportation mask mandate going into effect.

Snowstorm postpones some business in Washington
The Washington, D.C. area is bracing for more ice after the city’s biggest snowstorm in nearly two years left the district in a blanket of snow on Monday.

The weather delayed all Senate votes Monday including one on Biden's homeland security secretary nominee Alejandro Mayorkas to Tuesday. It also delayed the start to in-person learning Monday in the District leaving students to continue classes online instead.
The president on Sunday night, after a day of flurries, tweeted he was "Grateful for the short commute on days like these" along with a photo of him walking on the White House portico.
Though the Senate has essentially taken a snow day, ten Republican senators are still scheduled to meet with Biden at the White House later Monday to pitch a counterproposal to his COVID-19 relief package costing about a third of the size.

Weather delays vote on Biden's homeland security secretary nominee
A Senate vote on Biden's nominee to lead the Department of Homeland Security, Alejandro Mayorkas, that had been scheduled for Monday was pushed back until Tuesday because of the winter storm hitting Washington.

Mayorkas, on the cusp of Senate confirmation following a 55-42 procedural vote to close off debate on his nomination Thursday, is expected to be the fifth Biden Cabinet pick to be confirmed. If confirmed, he will be the first Latino and the first immigrant to lead the agency in charge of implementing the nation's immigration policies and border laws.
A former deputy secretary at the Department of Homeland Security, Mayorkas would return to the agency at a critical time for national security between the ongoing coronavirus pandemic and warning of domestic terror in the wake of the Capitol siege.

Biden to discuss pandemic relief with 10 GOP senators at White House
Ten Republican senators are slated to meet with Biden at the White House Monday at 5 p.m. after requesting the chance to pitch to the president their compromise to his COVID-19 relief bill, or as the Biden team has branded it, the "American Rescue Plan."
The GOP counterproposal, with a $617 billion price tag, costs about a third of Biden's $1.9 trillion proposal. The senators' plan keeps $160 billion for vaccine distribution but would more strictly target relief checks to those making less than $50,000 instead of $99,000 as with the previous two rounds. It does not include relief for state and local governments.

Democrats, who narrowly control the Senate with Vice President Kamala Harris' tie-breaking vote, are moving to use special budget reconciliation rules to pass Biden’s package with a simple majority. Biden has said he hopes for unity and a bipartisan effort, but he's also a plan must pass, "no ifs, ands or buts."
Over the weekend, Senate Majority Leader Chuck Schumer also said he hopes COVID-19 relief will be bipartisan but made clear Democrats are prepared to move forward on their own -- and with a plan which would include funding for state and local governments.

With just a week until former President Donald Trump's second impeachment trial begins, the former president has a new legal team after all five of his previous lawyers quit over strategy disagreements. Trump's previous legal team wanted to argue the constitutionality of impeaching Trump after he has left office, while Trump wanted his team to argue there was election fraud. His new lawyers are David Schoen and Bruce L. Castor Jr.
The White House will hold a press briefing with its COVID-19 response team Monday at 11 a.m. and a briefing with White House press secretary Jen Psaki at 12:30 p.m.
