NATIONWIDE -- ESPN has suspended SportsCenter anchor Jemele Hill.

In a statement, the network says, "Jemele Hill has been suspended for two weeks for a second violation of our social media guidelines. She previously acknowledged letting her colleagues and company down with an impulsive tweet. In the aftermath, all employees were reminded of how individual tweets may reflect negatively on ESPN and that such actions would have consequences. Hence the decision.”

On Twitter last month, Hill called President Donald Trump a "white supremacist," and called for a boycott of the Dallas Cowboys after owner Jerry Jones said the team would stand for the national anthem.

It is unknown which tweets in particular led to her suspension.
