A spokeswoman says Huma Abedin welcomed son Jordan Zain Weiner on Wednesday.
The delivery happened ten days before her New Year's Eve due date.
Sources say the baby boy weighed in at just more than seven pounds.
Weiner resigned from Congress in June amid outrage over sexually explicit emails and social media postings involving a former porn actress and other women. Republican Bob Turner won a special election to represent his Brooklyn-Queens district.
Abedin is a top aide to Secretary of State Hillary Rodham Clinton.
Weiner and Abedin married in July 2010. Jordan is their first child.
