PORTLAND -- Hours before former Vice President Al Gore was scheduled to speak at Keller Auditorium Wednesday, someone sprayed graffiti on the downtown Portland building.
The graffiti had messages that appeared to target Gore's environmental views. The steps of the auditorium were tagged with this message "Change the system not your lightbulbs." The front of the building was spray-painted "Don't buy false solutions" and the side of the building read "Climate justice not CO2 trading" in large black lettering.
It was unclear who tagged the building. Portland Police officers were investigating and called out a crew to clean up the graffiti before the former Vice President's arrival.
But at least two groups planned on protesting Gore's visit. PETA said it would confront Gore Wednesday, before his environmental speech called "Our Choice" -- a call to action against global warming. The group said the former Vice President should be a vegetarian because eating meat contributes to global warming.
Another group called "Americans For Prosperity" also planned to hold an event critcizing Gore's global warming views.
Gore's speech at Keller Auditorium was scheduled for 7:30 p.m Wednesday. On Thursday, the former Vice President was scheduled to headline a fundraiser for Democrat Bill Bradbury's campaign for governor. That event will start at 10:30 a.m. in North Portland.
