Wilmington, Delaware | Joe Biden has interviewed each candidate on his vice-presidential short list, and his advisers are planning an announcement for the middle of the week, people briefed on the selection process said on Monday (Tuesday AEST).

In a sign that the choice is now in Mr Biden's hands alone, the four-member committee that screened his potential running mates is said to have effectively disbanded — its work is complete, Biden allies said, and there is little left to do except for Mr Biden to make up his mind.
