"This was part of a pattern of behavior with this particular bus driver, not an isolated incident," Barry said.

Following the incident, Congressman Dave Reichert called Barry and told her that he and the President had seen the gesture. Barry said she personally knows Reichert from his days serving as King County Sheriff when they discussed school resource officers. Reichert called as a courtesy, Barry said.

"He never discussed his view or suggested what action he thought would be appropriate to take," Barry said. "He reported the incident believing -- rightly -- that I would want to know this occurred, that as a steward of children and public resources, one of my employees had acted inappropriately in her job capacity."

Barry reiterated that the decision to terminate the employee was not motivated by any political reason.

"If the bus driver had made the gesture to a driver who cut her off on a local road, we would have taken the same action," Barry said.
