(CNN) - Vice president-elect Joe Biden will travel to Southwest Asia later this week on his final overseas trip as a sitting member of Congress.
In a statement released today, Biden's office said he was traveling with the bipartisan group in his capacity as outgoing chairman of the Senate Foreign Relations Committee.
"The purpose of this trip is fact-finding: in the coming months both the Executive and Legislative branches will carefully review U.S. policy toward this region, and the trip will allow its participants to bring current and first-hand information to these reviews," said Biden spokeswoman Elizabeth Alexander.
Members participating in the trip include incoming Foreign Relations Committee chairman John Kerry, along with Democratic Sen. Jack Reed of Rhode Island Republicans Susan Collins of Maine and Lindsey Graham of South Carolina.
Biden's office also said the delegation "will make it clear to foreign leaders that they are not there to speak on behalf of the U.S. government, or convey policy positions for the incoming administration." Details of the journey will be released as the trip progresses, for security reasons.
