From his office in the White House, President Josiah Bartlet (series star MARTIN SHEEN) leads the most powerful nation on earth. Directly descended from one of the signers of the Declaration of Independence, New Hampshire Democrat Bartlet exudes a country-lawyer charisma that complements his brilliance, his deep conviction and his devotion to what he believes is right for the country. A brilliant academician in her own right, first lady Dr. Abigail "Abbey" Bartlet (series star STOCKARD CHANNING) staunchly supports her husband but does not hesitate to keep him in line when necessary. As always, professorial Chief of Staff Leo McGarry (series star JOHN SPENCER) resolutely serves as Bartlet's political and emotional right hand, while Deputy Chief of Staff Josh Lyman (series star BRADLEY WHITFORD) keeps his highly regarded political mind in overdrive. Donna Moss (series star JANEL MOLONEY), Josh's capable assistant, more than holds her own in their friendly verbal sparring.
