Washington (CNN) White House press secretary Sarah Sanders will leave her position at the end of the month, capping a tumultuous tenure as the President's chief spokeswoman in which she largely redefined the role.

President Donald Trump announced on Twitter that Sanders will return to her home state of Arkansas and floated the possibility of a gubernatorial run for the White House press secretary. Speaking at an event later Thursday afternoon, Trump praised her as a "warrior."

The descriptor reflected both the combative nature of Sanders' tenure and extent to which Trump has admired her pugnacity amid a fire hose of controversies. Her departure leaves Trump without one of his chief public defenders, longest-serving advisers and closest aides.

The announcement of her exit, which coincided with the 94th day since she last appeared at the podium, also cast a spotlight on the scope of change she ushered in, offering a vanishing degree of accountability to the position.

Speaking at an event shortly after the announcement, Sanders called her role "the honor of a lifetime" and an experience she "will treasure forever."
