WASHINGTON — The White House kicks back into campaign mode on Tuesday as Vice President Biden raises money for Democrats in the South.

Biden is due in Tulsa, Okla., in the evening for a Democratic National Committee event. That’s after he heads west to speak at a clean energy conference in Las Vegas.

A review of Biden’s public schedules for recent weeks shows that he hasn’t spoken at a DNC fundraiser since July 25, when he raised money at a Washington hotel during the deficit negotiations. Obama last spoke at a fundraiser on Aug. 8, at the same place — the St. Regis Hotel.
