up to 8,000 protesters Friday on Inauguration Day
and Mayor Ted Wheeler is calling on people to do so peacefully.
“We have an opportunity this week to show the rest of the nation that we are a community that is very active and very engaged but we’re also peaceful,” Wheeler said at a press conference Wednesday.
Demonstrations will also take place in Eugene, Bend and other cities around the country.
Women's March A day after the inauguration, more than 34,000 people have RSVP'd on Facebook to attend the women’s march in Portland. The march will wind through 44 blocks of downtown Portland. Organizers have a permit and are coordinating with police.
Oregon Congressmen Won't Attend Democratic Reps. Earl Blumenauer and Kurt Schrader said they will stay in Oregon and participate in events critical of the incoming president instead of attending the inauguration.
"He hasn’t proved himself to me at all yet, so I respectfully decline to freeze my ass out there in the cold for this particular ceremony," Schrader said.
What's In Store For The Northwest? Following the election, the Associated Press called Oregon the "epicenter" of the anti-Trump energy in the U.S. But will this be the case moving forward? Although Hillary Clinton won Oregon, parts of the state strongly supported Trump.
