The sources did not say why Brookover was fired.

Brookover, who joined the Trump campaign in March, was appointed in June to serve as a liaison between the Trump campaign and the Republican National Committee.

Prior to joining Trump, Brookover served as campaign manager to Ben Carson during his failed bid for the Republican nomination.
