The President of the United States has the authority to nominate members of the cabinet to the United States Senate for confirmation under Article II, Section II, Clause II of the United States Constitution.
This page documents the nomination and confirmation process for any successful or unsuccessful cabinet nominees of Barack Obama's administration. They are listed in order of creation of the cabinet position (also used as the basis for the United States presidential line of succession).
The Vice President is an elected official rather than an appointed position, and therefore does not require confirmation by the Senate.
Since shortly following Biden's withdrawal from the presidential race, Obama had been privately telling Biden that he was interested in finding an important place for him in a possible Obama administration. In a June 22, 2008, interview on NBC's Meet the Press, Biden confirmed that, although he was not actively seeking a spot on the ticket, he would accept the vice presidential nomination if offered. In early August, Obama and Biden met in secret to discuss a possible vice-presidential relationship. On August 22, 2008, Barack Obama announced that Biden would be his running mate.The New York Times reported that the strategy behind the choice reflected a desire to fill out the ticket with someone who has foreign policy and national security experience—and not to help the ticket win a swing state or to emphasize Obama's "change" message. Other observers pointed out Biden's appeal to middle-class and blue-collar voters, as well as his willingness to aggressively challenge Republican nominee John McCain in a way that Obama seemed uncomfortable doing at times. In accepting Obama's offer, Biden ruled out to him the possibility of running for president again in 2016.
