The Clinton State Department had Washington power couple Phil and Melanne Verveer in senior positions: she as ambassador-at-large for global women’s issues and he as coordinator of international communications and information policy.

The Kerry State Department also may boast its own dynamic duo. There’s chatter that Dan Sepulveda, who was on Secretary of State John Kerry’s personal staff, is moving off the Hill to Foggy Bottom to replace Phil Verveer.

Sepulveda, who worked for President Obama when he was a senator and was an assistant U.S. trade rep, joined Kerry’s Senate staff in late 2009 to work on communications, commerce and trade matters. He’s now working for temporary Sen. William “Mo” Cowan (D-Mass.).

Sepulveda is the long-time (some 14 years) boyfriend of Heather Higginbottom, former deputy director of the Office of Management and Budget. Higginbottom, who had been Kerry’s legislative director in the Senate, was recently tapped by him to be his counselor.
