WASHINGTON, D.C. – A mob of angry high school students descended on Trump International Hotel in downtown D.C. Tuesday, including some from the prestigious Sidwell Friends School attended by President Obama’s children and those of other U.S. elites.

A YouTube video posted online shows students climbing statues and windows on the building as hundreds screamed about racism, misogyny, sexism and other social justice causes in the second day of protests against President-elect Donald Trump, NBC Washington reports.

“Young people who said they went to Benjamin Banneker Academic High School, Woodrow Wilson High School and Sidwell Friends School in Northwest D.C. protested outside of Trump International Hotel in downtown D.C.,” the news station reports.

“The students began to march to the Capitol Building around 1 p.m. Police said they were monitoring the demonstrators and establishing rolling road closures as needed.”

The YouTube video shows the crowd of several hundred students erupt into a frenzy when a girl climbed on the window at the hotel and hoisted an anti-Trump protest sign overhead before waiving her middle finger. Others climbed on the building and waived a rainbow flag, NBC Washington reports.

Moments later, the mob broke into the chant “Trump is a chump.”

Students in front of the hotel waived signs that read “Love trumps hate,” “My body, my rules,” and “climate change is real.”

After several minutes of screaming and sign waiving, a young man climbed a statue of Benjamin Franklin in front of the private building. A few minutes later, students yelled, “take the streets” and many marched off.

The demonstration Tuesday was the latest by students at seven area high schools over the last two days, though it was notable because it included students from Sidwell Friends and Benjamin Banneker schools.

Sidwell Friends, described by the New York Times as “the Harvard of Washington’s private schools,” counts President Obama’s children, Sasha and Malia, as well as Vice President Joe Biden’s grandchildren, among its students. Sidwell – which costs about $40,000 a year, according to its website – has also educated the children political elites like Theodore Roosevelt, Richard Nixon, Bill Clinton, Al Gore and others.

Banneker is a small prestigious selective enrollment magnet school located across the street from Howard University that’s regarded by many as the top public high school in D.C.

Yesterday, about 800 students from nearby Montgomery Blair High School walked out of class and were ushered to the school’s football field, where school officials hoped to contain the protest, Montgomery County Public Schools spokeswoman Gboyinde Onijala told the news site.

Some of the students went back to class, while others left school property to march to downtown Silver Spring chanting “We reject the president-elect,” “not my president,” and “no justice, no peace.” The Blair students were joined by others from Northwood High School and Albert Einstein High School.

“We’re not protesting for a new president,” one student said. “We’re protesting to have our voices heard.”

That protest fizzled out after about an hour.

Woodrow Wilson High School Principal Kimberly Martin issued a letter to parents that defended students’ right to protest, but warned that those who miss school will receive an “an unexcused absence for the periods they miss,” NBC Washington reports.
