UPDATE: It's official. The word came first via Obama's web site and shortly thereafter a text message went out to supporters stating, "Barack has chosen Senator Joe Biden to be our VP nominee."ABC News' Jake Tapper is
reporting that the Secret service is en route to Sen. Joe Biden's Delaware home, indicating that Sen. Barack Obama has chosen Biden to be his running mate.
The United States Secret Service has dispatched a protective detail to assume the immediate protection of Sen. Joseph Biden, D-Del., a source tells ABC News, indicating in all likelihood that Biden has been officially notified that Sen. Barack Obama, D-Illinois, has selected him to be his running mate.
Sources also tell ABC News that two others said to be finalists for the position of Obama's running mate -- Sen. Evan Bayh, D-Ind., and Virginia Gov Tim Kaine -- have been told they have not been selected for the vice presidential slot.
Kaine flew to Denver earlier today, is in Denver tonight and has no plans to leave in the next 24 hours. Bayh is at his Washington, DC, home with his family.
Biden was last seen minutes ago at his Wilmington estate where his extended brood is gathering.
Until the official announcement is made, around 10 AM tomorrow morning by text message, all reports on the selection are conjecture. However, unless the Secret Service is participating in an Obama campaign head fake, this report seems as solid an indication of Obama's selection as there can be.
