"I have ased Senator Schumer, whose communications abilities and tactical skills we all greatly respect, to lead this office," Reid wrote.
Schumer, the number three man in the Democratic leadership, will be backed up by Sen. Debbie Stabenow (D-MI), who currently serves in leadership as Steering and Outreach Committee chair. The vacancy will be filled by Sen. Mark Begich (D-AK), a freshman who's actively organized with other first-term Democrats to give junior members more influence in the caucus. He'll be the fifth-ranking member of Democratic leadership.
