This was a lengthy tweetstorm.
Yesterday, ESPN suspended Jemele Hill for two weeks after she suggested people consider boycotting sponsors of the Dallas Cowboys following Jerry Jones' comments about protesting NFL players.
This morning, the president went after Hill on Twitter.
Hill's ESPN colleague Sarah Spain went on a long Twitter rant today defending her co-worker and expressing her feelings on the president and other current issues.
Spain is usually pretty outspoken on Twitter, so it's not too surprising she commented on this.
