Protesters refused to share their march plans with the Portland Police Department and said they would march through the streets as they please. The crowd shouted: "Whose street? Our street!"
Police, dressed in riot gear, mostly stood at a distance from the protesters, but would not allow them to cross any of the numerous bridges across the Willamette River running through the middle of the city, which would shut down traffic in and out of the city.
Protesters chanted "I don't see no riot here, Take off your riot gear!" when marching past police formations.
After the November presidential election, which saw Trump beat Hillary Clinton, Portland saw violent protests that resulted in millions of dollars in damage to public and private property.
After the elections, Portland also received a new mayor, Ted Wheeler, who on Friday said there would not be a repeat of those protests back in November of last year that turned violent.
There were several reports of projectiles, mainly ice balls and eggs, being hurled at police. Police reacted by dispersing pepper spray in the direction the projectiles were launched.
"In response to questions: Police have only deployed pepper spray during this march (No tear gas)," the Portland Police said on its Twitter account during the protest.
Protests in Portland are expected to continue through the night.
