Hillary Clinton campaign headquarters expected Brooklyn Heights office building in New York

Hillary Rodham Clinton has signed a lease in a Brooklyn, New York, building for what is expected to house her presidential campaign headquarters.

A person familiar with the plans says Clinton has signed the lease for two floors in an office in New York's Brooklyn Heights neighborhood. The person spoke on condition of anonymity and was not authorized to speak publicly about internal planning.

Clinton is expected to announce her presidential campaign in the coming weeks, and the decision to sign the lease likely sets off a 15-day period in which presidential candidates are required to make their intentions known.

The building also houses the U.S. attorney's office of Loretta Lynch, who has been nominated to be President Barack Obama's next attorney general.

The lease was first reported by Politico.
