Ballard High School, Chief Sealth International High School and Highline High School will all participate in a school walkout on April 20, the anniversary date of the Columbine mass shooting in 1999. This is the second walkout demanding gun law reforms in recent weeks.

The walkout will begin at 10am and likely last approximately less than 30 minutes.

Students will gather outside and observe a moment of silence, while others in more than 2500 schools nationally will  march to local lawmaker's offices, let students speak and help register those who are eligible to vote.
