Joe Biden’s team will start receiving intelligence briefings from the Pentagon starting today as the presidential transition gets further underway. Biden is also set to meet for the first time with the White House chief vaccine adviser, Moncef Slaoui, this week.

Meanwhile, Biden has tapped California Attorney General Xavier Becerra to lead the Department of Health and Human Services. Becerra has filed at least 100 lawsuits against Trump, including against his immigration and environmental policies. He led the fight, alongside 20 other states and Washington, D.C., to defend the Affordable Care Act as it was being attacked by Trump and the Republican Party. He has also voiced support for Medicare for All in the past. Becerra previously served as a Los Angeles congressmember and was the first Latino to serve on the Ways and Means Committee.
