WLNI-MCHRISTIANSBURG, Va. (AP) _ About 20 students at a Virginia high school received a one-day suspension for wearing clothing displaying the Confederate flag. Montgomery County Public Schools spokeswoman Brenda Drake says the clothing violated Christiansburg High School’s dress code. Drake says the students refused to comply with the dress code after they arrived at the school Thursday in the clothing. They were given one-day in-school suspensions. But she says a majority of the students didn’t follow in-school suspension rules and were given out of-school suspensions. Confederate symbols have come under increased public scrutiny since the June 17 massacre of nine black worshippers at a church in Charleston, South Carolina. The man charged had been photographed holding the Confederate battle flag.
