3:21 p.m.: Anna Jackson, 33, of Portland has a 13-year-old eighth-grader at DaVinci Middle School. She met up with her daughter at Portland City Hall, and they have been walking with the protesters since. "I stayed with the kids to make sure no harm came of them," she said after the protest. She screamed at the woman who got into the protesters' faces. "I support freedom of speech, but it shouldn't include hate speech. I think freedom of speech ends when you start oppressing someone. At worst, you should be locked up. At best, you should receive counseling." Jackson said she was proud of the students for protesting without violence. "They accomplished something the adults in this city haven't done yet."

3:18 p.m.: Dozens of people arrested during the past week of anti-Trump protests crowded the second floor courtrooms of the Multnomah County Justice Center, where they made their first appearances in court. In all, at least 113 people have been arrested for charges including second-degree disorderly conduct, interfering with police and riot. The first wave was arraigned Monday, and the second wave are scheduled to appear in court Tuesday. Those arrested and their supporters packed the courtrooms until there was standing room only, and others had to wait out in the hall. They told stories of how they thought there were wrongfully arrested by police for exercising their rights to free speech. Monday, at least 20 people learned that their charges are being downgraded from misdemeanors to citations -- similar to a traffic ticket. They were given court dates for their next appearances. Eighteen of those arrested learned the the Multnomah County District Attorney's Office is not pursuing criminal charges against them at this time. But the District Attorney's Office warned that doesn't mean those arrested are off free: Criminal charges could still be pursued after police -- who were "working to protect the city during an emergent event" -- haven't had time to write police reports, according the a joint statement released by prosecutors and police. Police also need time to comb through video evidence. "The sheer number of arrests during protests over the last several days has been an exceptional event and the charges being 'no complainted' today is not unexpected and is a procedural matter given the extensive amount of work left to do in these cases," the joint statement read. Nearly all of those arrested will receive -- if they haven't already -- a citation accusing them of failing to obey a police officer.

3:09 p.m.: The protest has ended, and students have left the park. Half a dozen remain, talking among themselves, and others are trying to catch a bus nearby. At the gazebo, students thanked the crowd for joining them, told everyone to have a good night, then they chanted, "No Trump, no KKK, no fascist USA."

3:03 p.m.: Dustin Johnson, a 40-year-old Portland resident, was riding at the tail end of the group with other adults who are making sure the students stay safe. He spoke with a reporter and said he has been participating in the Portland protests in the past week. "This is great. I think everyone should be protesting right now. Their voices need to be heard too, even though a lot of them are probably not even 18 yet. It's great to see them exercise their right."

2:43 p.m.: A woman who saw the protesters and pulled her car over. She began chanting, "We won, you lost." She also shouted "all lives matter," and told marchers to get over it. Thumbs down, says "President Trump," she said. Students shouted back at her.

2:41 p.m.: The group arrived at Jefferson High School, where it began chanting, "Join our protest!" A few students emerged from the school, then the demonstrators headed along North Killingsworth Street toward Portland Community College Cascade Campus.

2:39 p.m.: An 18-year-old man who police say drove a car onto the Morrison Bridge early Saturday morning, stopped to let a 14-year-old passenger shoot an anti-Trump protester, then drove off appeared in Multnomah County Circuit Court on Monday afternoon. Shamar Xavier Hunter is accused of aiding and abetting an attempted murder and unlawful use of a weapon. Hunter was arraigned via closed circuit TV, from a room within the Multnomah County Jail. Supporters of Hunter sat in the audience of the courtroom, looking concerned. Although Hunter remains in jail on more than $1.5 million bail, Judge Karin Immergut ordered he have no contact with a list of victims, though the judge didn't elaborate on the victims.

2:35 p.m.: The 14-year-old boy arrested in connection with early Saturday's shooting of a protestor on the Morrison Bridge made a brief appearance Monday afternoon in juvenile court before Juvenile Referee Lisa Fifthian-Barrett. He was arraigned on allegations of attempted murder, second-degree assault with a firearm and unlawful use of a weapon. He remains in custody at the Donald E. Long Detention Home and is scheduled back in court later this month. Because he is 14, he is not facing Ballot Measure 11 prosecution.

2:15 p.m.: Police say a 14-year-old boy has been arrested in the shooting early Saturday on the Morrison Bridge as the protest that night was ending. He faces accusations of attempted murder for allegedly wounding a protester in the leg when the demonstration blocked traffic on the bridge. An 18-year-old, Shamar Xavier Hunter, will be arraigned this afternoon. He's suspected of being the driver in the shooting, police said. A second 18-year-old who was initially arrested was released from jail. Police said he wasn't involved in the shooting.

2:10 p.m.: TriMet announces that the protests could delay the MAX Yellow Line, which runs along Interstate Avenue between the Expo Center in North Portland and downtown, as well as the Orange Line.

2:04 p.m.: The group is continuing north on Interstate. Some students are taking various bits of clothes off. At least one student is in her bra and underwear. A police officer, who sounded like a woman, admonished the students over a loudspeaker to remember that "we are still ladies," and that behavior is not "ladylike."

1:47 p.m.: A moment of silence at Interstate and North Greeley Avenue. Students at front of the pack say the silence, 4.5 minutes, represents the hours Michael Brown lay dead on the street.

1:35 p.m.: Students are walking north along North Interstate Avenue. A police officer tells an Oregonian/OregonLive photographer: "It's now becoming an unpermitted march."

1:07 p.m.: The group, which has thinned to about 200, has left the mall and are heading along Northeast Multnomah Street and crossing Martin Luther King Jr. Boulevard. After a quick stop at the Moda Center, they're off again. The students have been chanting, "No Trump, No KKK, No fascist USA," "If we don't have no justice, then you don't have no peace," "My body, my choice," "Black Lives Matter," "Whose streets? Our streets." A sign reads, "We want our voices heard." Another sign has a drawing of Hillary Clinton accompanied by the hashtag "#MrsPresident"

Here is a video compliation from today's student march:

12:50 p.m.: Grant High School officials confirm that Student Body President Lilly Sasse and Vice President Christina DePinto wrote a letter to students discouraging them from participating in Monday's walkout. Instead, they and other student leaders from Portland area high schools developed Unity Week as an alternative. The week's theme's include places for safe communication and discussions, a safe and inclusive environment, unity and positivity, among others. Concerning bypassing Monday's walkout, the student leadership group Portland Metro High School Youth Alliance wrote:

We want to strongly encourage everyone NOT to participate in the walkout on Monday. We value each student's voice, and right to protest, but we don't want a powerful message to get lost in something that lacks clarity, organization and a consistent message. We also are aware of the recent protests that have resulted in some violence and destruction, and we don't want to run the risk of feeding into that narrative. We must also be mindful of schools and people who have different lived experiences than our own. ... It is also important that we organize in a way that allows every student, teacher and community member to be involved without feeling alienated. Leaving our valued education is not the way to send that message.

12:45 p.m.: Students swarming all over Lloyd Center shopping mall.

12:34 p.m.: Police have accompanied the crowd throughout the march, handing out Portland Police stickers to students. Earlier police estimates put the crowd at between 300 and 400, but it appears largers in Holladay Park, after Benson students joined. One student is addressing the crowd with a megaphone; other students have a large white banner spray-painted to read, "Love Trumps Hate."

12:31 p.m.: Holladay Park near Lloyd Center is the next destination.

12:20 a.m.: The group arrived at Benson High School and began yelling, "Walk out, walk out!" It appears to be working as students are emerging from the building.

11:53 a.m.: The students have reached Southeast 7th Avenue and Main Street.

The group passed a gym called Inner Beast Strength and Conditioning at Southeast 6th Avenue and Madison Street. Shay Emmons, who owns the gym, saw the students pass and told an Oregonian/OregonLive reporter: "This is honestly the best thing I've seen all week. It makes me want to cry, I'm so happy right now."

Emmons, who stood outside the gym applausing with clients she was training, said the action gives her hope for the future to see young people stand up and protest.

11:35 a.m.: Some students began climbing up the bridge, but others yelled for them to get down and they climbed off.

Peter Fink, a Cleveland sophomore, says he's demonstrating "because Hillary won the popular vote. She won by more than 1.7 million votes, and that's not right." Fink said that's not a democracy, "that's a republic, and I want a democracy."

More than 100 students walked out of school and began protesting Monday morning in Pioneer Courthouse Square, the latest demonstrations to develop after the election of Donald Trump as president.

The gathering is one of many reportedly being organized by students across the metro region.

Students at the gathering have said they are from Benson High school, the Metropolitan Learning Center and Cleveland High School.

Mori Ono, a seventh-grader at Metropolitan, said the students are protesting because they don't support Donald Trump, saying, "They think he's fascist."

Bridget Fanning-Ono, More's mom, said she thinks it's positive that the kids are protesting but doesn't know what it will accomplish. She is, however, supportive of their passion and hopes they will somehow influence hateful rhetoric.

This story will be updated as developments occur.
