Washington, D.C. has been secured by 25,000 National Guard troops this week in preparation for the inauguration of President-Elect Joe Biden Wednesday. The security concerns increased after a January 6 riot at the U.S. Capitol.

The riot took place after President Donald Trump spoke to his supporters and encouraged them to make their voices heard in front of the Capitol as Congress was certifying the Electoral College results, making Joe Biden the President-Elect.

Rioters then broke windows, entered and looted the building. The chaos resulted in 5 deaths.

Trump later clarified that he was encouraging a peaceful protest and condemned the violence.

Since then, the city has been on high alert as National Guardsmen from dozens of states pour in to assure a peaceful event.

However, amid concerns of potential violence, a number of schools across the country have reportedly opted to not show students the live inauguration ceremony.

That includes the Keller Independent School District in Dallas, Texas, which is allowing parents to excuse their students from class during the live stream, according to the Dallas Morning News.

According to the Bangor Daily News, the Bangor School Department in Maine says it won’t show the event to students “due to the threat of potential violence.”

New York’s Ossining Union Free School District in New York won’t show the inauguration to “ensure the social and emotional well-being of our students,” according to a letter from the school district’s superintendent.
