For the second time in recent months, the Baldwin County School System finds itself investigating a politically-charged incident at one of its schools.

The latest involves a picture, shared on social media Saturday, of two Robertsdale high school students standing and smiling with the school's mascot. One of the girls is holding a President Donald Trump political sign, that reads "Making America Great Again." The other is holding a homemade sign that reads, "Put the Panic Back in Hispanic."

"We are aware of a photo that appears to be taken at a Robertsdale High School football pep rally Friday, Sept. 15, that is circulating on social media containing political banners and unacceptable language," Baldwin County Superintendent Eddie Tyler said in a statement. "School administrators, as well as my office, are following up on the matter."

The photo stoked criticism on Facebook and Twitter. One current student said she is "sad" to be a member of the senior class, and others demanded the school system and Robertsdale high school officials be held accountable.

Krystal Austin Moore, who identifies herself as a former class president, shared the photo on Facebook and claimed she was "confused" as to why the banners were acceptable at a public high school.

"I experienced very underhanded racism on several accounts as a student, but never in my lifetime would I imagine this would still be penetrated into the student body on this level at my beloved alumni," she wrote.

Robertsdale has the largest percentage of Hispanics of any city in coastal Alabama, with 9.2 percent of the city's 5,990 residents identifying as Hispanic or Latino, according to 2010 U.S. Census data.

Baldwin County, on average, is 4.4 percent Hispanic. Alabama, according to 2010 Census figures, is 4.2 percent Hispanic.

The school system's investigation into the Robertsdale incident comes while Tyler and his staff examine a complaint from a Spanish Fort high school student about a "culture of bias and discrimination" at the school.

The complaint from Julia Coccaro, a high school senior and chairwoman of the Alabama High School Democrats, stemmed in part from a controversy in June over a summer reading list produced by AP Government teacher Gene Ponder filled with works by various conservative political heroes and right-wing firebrands. Among the authors were Mark Levin, Michael Savage and Ann Coulter.

Tyler said in June he wasn't concerned with the content on the list. Instead, he was more upset that Ponder did not follow the school system's policies in getting the list approved. The list was subsequently removed.

Coccaro, during a School Board meeting last month, publicly asked for an updated into her complaint, but was told it was ongoing. She also criticized School Board President Shannon Cauley for being "extremely patronizing" toward her after Cauley told Coccaro to do more research about her rights as a student when it comes to free speech.
