Cody Alicea rode with dozens of veterans, some from out of state, as he biked to Denair Middle School. They all carried American flags on their bikes to show their support.
Last week, school officials told Cody he should not put the stars and stripes on his bike because some students were offended. The school superintendent has apologized.
"The bottom line, I am the superintendant of DUSD. This shouldn't have happened," Superintendent Ed Parraz said.
"They said some students were complaining. It was Veterans week so I was kind of confused. I'm flying your country's flag to support veterans and on Veterans week they told me I couldn't fly it," Cody said.
Cody says he put the flag on his bike a couple of months ago and never had a problem until recently.
The school district is now facing a lawsuit from a civil liberties group.
