Credentials: More than three decades in top jobs on Capitol Hill. Most of that time, it was as chief of staff to Thomas A. Daschle (D-S.D.), a former Senate majority leader. When Daschle lost his seat in 2004, Rouse agreed to serve in the same role for Obama, then helped with his presidential campaign.
What he offers: His substantial influence on the Hill is legendary -- Rouse, 62, was sometimes called the 101st senator because of his influence. His reputation as a publicity-averse workaholic fits in well with the team Obama is creating.
Vetting: Such a Washington insider at the center of the West Wing may not jibe with Obama's vow to shake up the ways of the capital.
