(CNN)-- Embattled senator Al Franken plans to officially resign from office Tuesday.
A spokesman for the Minnesota Democrat announced last month that Franken would leave the senate January 2nd.
Franken announced his plans to resign in December after multiple women accused him of sexual harassment and other inappropriate behavior.
His successor, Minnesota lieutenant governor Tina Smith, will be sworn into office Wednesday.
A special election will be held in November to serve out the final two years of Franken's term.
