Serena Williams tells Tennys Sandgren to apologise for controversial tweets
The unheralded American has come under increased scrutiny over his political views after run to Australian Open quarter-finals

Serena Williams has called on Tennys Sandgren to apologise after the unheralded American exited the Australian Open amid a backlash over his political views.
Sandgren, a devout Christian, bowed out of the quarter-finals in Melbourne in straight sets following scrutiny over his politics and apparent support for far-right groups in the US.
Williams had been the subject of a Sandgren post on Twitter, with the 26-year-old describing the former world number one’s behaviour during a 2015 US Open match against Roberta Vinci as “disgusting”.
Williams, who on Tuesday confirmed her comeback at the Fed Cup next month following a near year-long absence because of pregnancy and subsequent birth of her daughter, ripped Sandgren in a post on Twitter on Wednesday.
Williams had earlier taken aim at Sandgren as the broadcast of his last eight defeat to South Korea’s Chung Hyeon got under way.
“Turns channel,” the 36-year-old star wrote.
