Sen. Chuck Schumer (D-N.Y.) is officially Senate majority leader after the inauguration of Vice President Kamala Harris and the swearing-in of new Sens. Alex Padilla (D-Calif.), Jon Ossoff (D-Ga.) and Raphael Warnock (D-Ga.).
Why it matters: With a 50-50 Senate, Schumer will control a narrow majority with Harris as the tie-breaking vote. Democratic control of the Senate is crucial to President Biden's agenda, from getting his coronavirus relief proposal passed to forgiving student debt.
