Police are investigating an overnight break-in at the Seattle office of the Washington State Democrats.

The office was the state headquarters for President Barack Obama's re-election campaign and Democratic candidate for governor Jay Inslee.

Police were called after a campaign staffer who arrived at the office early in the morning found a broken window and open door.

At least two laptop computers were missing from the office and some property was damaged, according to Democrats.

Police spokesman Mark Jamieson said it wasn't clear if the burglary was politically motivated. Police do not have a suspect at this time.
