The U.S. Senate has joined calls for Brazil to return a boy living there to his father in New Jersey.
Lawmakers unanimously passed the resolution late Tuesday.
The boy's mother took him on a vacation in 2004 and never returned to the U.S. She divorced his father and remarried but died last year.
The father, David Goldman, says Brazilian courts have denied him custody of the 8-year-old. The child is being raised by his stepfather.
Secretary of State Hillary Clinton and the New Jersey State Senate have also called for the boy's return.
The presidents of the U.S. and Brazil discussed the case this month.
