A North Texas school board member revealed that a letter encouraging anti-racism led to a Black principal being fired from a mostly white high school.

Tammy Nakamura, a newly elected member of the Grapevine-Colleyville school board, told a Republican National Committee-sponsored school board panel about how former Colleyville Heritage High School principal James Whitfields role as an activist was the straw that broke the camels back, The Daily Beast reported .

Whitfield wrote a letter to his school in the early morning hours of June 3, 2020, in the wake of protests related to George Floyds death.

In the letter, he said education was the key to ending ignorance, hate and systemic racism, according to The Texas Tribune .

Its a necessary conduit to get liberty and justice for all, he wrote.

Over a year after his remarks, Stetson Clark, a former school board candidate, referred to the letter at a school board meeting and accused Whitfield of teaching critical race theory.

He is encouraging the disruption and destruction of our district, Clark said. The crowd cheered as he finished his remarks.

Whitfield, the first Black principal at a mostly white high school, was placed on paid administrative leave in August 2021. He agreed to resign as principal, but will remain on paid administrative leave until August 2023, The Texas Tribune reported .

Part of the districts settlement with Whitfield includes an agreement to resolve disputes and not make any additional public statements, the Fort Worth Star-Telegram reported .

Nakamura said Whitfield was a total activist and referred to the letter he wrote in response to Floyds death.

There is absolute proof [of] what he was trying to do, Nakamura said. They have to be stopped now, we cannot have teachers such as these in our schools because theyre just poison, and theyre taking our schools down.

Nakamura also claimed Whitfield brought national media exposure to the Grapevine-Colleyville school district because he was married to a white woman.

Nakamura and other Grapevine-Colleyville school board members did not immediately respond to a HuffPost request for further comment.

The board has a meeting scheduled for Monday with an executive session to deliberate the appointment, employment, evaluation, reassignment, duties, discipline or dismissal of a public officer or employee or to hear complaints or charges against a public officer or employee, according to the Fort Worth Star-Telegram.
