PORTLAND, Ore. -- For the fifth straight night, a group of protesters have marched to show their opposition to Donald Trump's election victory.

Protesters initially met at Pioneer Courthouse Square at 6 p.m. Saturday night before beginning their march at around 6:45 p.m. The group of a couple hundred protesters is much smaller than previous nights, when there were thousands of protesters.

Police said the march is not permitted.

Earlier Saturday, Mayor Charlie Hales and Police Chief Mike Marshman urged protesters to stay home and to voice their displeasure with Trump's election in other ways.

“Going to the streets for another night is not going to keep Donald Trump from taking office. It isn’t going to change anything,” said Hales.

“If you’re upset with the election, please don’t come out and protest,” he said. “We are done with criminal activity in this city. It’s time to move on and to move forward.”

The pleas from Hales and Marshman came after four nights of protests and riots, in which traffic was disrupted, buildings vandalized, one person shot and more than 40 people arrested.
