Cable sports network ESPN on Monday suspended broadcaster Jemele Hill for violating its social media guidelines for the second time in the past month after she tweeted on NFL player protests.

Hill on Sunday said football fans should boycott advertisers of the Dallas Cowboys if they were offended by team owner Jerry Jones? threat to bench players who did not stand during the national anthem.

ESPN said in a statement it had suspended Hill for two weeks for the second violation.

It said she ?previously acknowledged letting her colleagues and company down with an impulsive tweet? last month when she called US President Donald Trump a ?white supremacist? who has surrounded himself with other white supremacists.

Hill is one of the hosts of SportsCenter ? ESPN?s sports news program. In a series of tweets on Sunday and Monday, she responded to Jones? comments about not playing anyone who was disrespectful of the US flag.

?Change happens when advertisers are impacted. If you feel strongly about JJ?s statement, boycott his advertisers,? Hill wrote on Twitter on Sunday.

On Monday, before her suspension was announced, Hill wrote, ?Just so we?re clear: I?m not advocating a NFL boycott.?

She went on to say that an unfair burden was being placed on players whose owners directed them to stand for the anthem.
