Senator Elizabeth Warren once bragged about being a “thorn” in the Obama administration’s side, a populist outsider who sparred with its key economic officials and sometimes broke publicly with the president.

When it comes to the Biden administration, she may be more of a voice in an ear.

President Biden is staffing his administration with numerous Warren-aligned figures who are delighting the left — including at least four of her presidential campaign staffers and some key proteges and allies. Even though Warren herself was passed over for roles like vice president or Treasury secretary, the appointments are a sign that some of her policy goals could come to fruition during Biden's presidency and that her views will have ongoing influence.
