The vice presidential possibility had been raised by Bill Clinton in the previous month, but this fueled speculation that Hillary Clinton was definitively interested in the possibility. "The New York Times" described the relationship between Obama and Clinton during the campaign as having "veered between strained and strange", and suggested that the manner in which Obama reacted to Clinton and her supporters would be a major test of the post-primaries period. By June 4, several media networks and top Clinton aides confirmed that she had been planning to concede the race for the Democratic nomination and endorse Obama. By June 5, the Clinton camp backed away from any suggestion about the vice presidential slot, with Clinton's spokesperson saying "[she] is not seeking the vice presidency, and no one speaks for her but her. The choice here is Senator Obama's and his alone." On June 7, 2008, in a speech before her gathered supporters at the National Building Museum in Washington, D.C., Clinton officially announced that she was suspending her campaign and was fully endorsing Barack Obama. Clinton said:  Clinton also adopted Obama's signature slogan, "Yes We Can", in her concession speech. Obama responded to the speech in a number of venues. Shortly after she gave it, Obama stated that he was "thrilled and honored" to be supported by Clinton. In North Carolina on June 9, 2008, Obama began his speech by praising Clinton. He stated:  Obama also thanked Clinton on his website and asked his supporters to do so as well via a special page designated for that task. In addition, at a rally in Michigan on June 16, Obama defended Clinton as she was being heckled by some members of the audience, stating that "she is worthy of our respect, she is worthy of our honor." The 2014 book "" says that as the campaign wound down, a handful of staffers were tasked with compiling a list of Democrats based on their perceived loyalty or disloyalty during the campaign. After conceding defeat to Obama, Clinton's name was mentioned exhaustively by speculators and party officials as a possible running mate for the Illinois senator; the potential ticket was dubbed "the Dream Team", "the Dream Ticket", and "the Unity Ticket" in some quarters. However, she was never seriously considered or vetted by Obama for the position. Ultimately, Obama selected Delaware Senator Joe Biden over Clinton and a number of other rumored candidates, including Texas Rep. Chet Edwards, Kansas Gov. Kathleen Sebelius, Indiana Sen. Evan Bayh (an early and prominent Clinton supporter), and Virginia Gov. Tim Kaine; the announcement was reported by CNN after midnight (U.S. Eastern Time) on August 22.
