A bomb-sniffing dog reacted to a minivan being used for Prime Minster Ehud Olmert's visit Monday, leading to a 90-minute evacuation of parts of a White House annex building.
Nothing suspicious was found in the vehicle, said Secret Service spokesman Dan Blackford.
Olmert was having meetings at the Blair House, the government guest quarters on Pennsylvania Avenue across from the White House, and his schedule was not affected, members of his delegation said.
The evacuated building was the White House conference center, on Jackson Place around the corner from Blair House. The conference center temporarily houses the White House press corps.
