PARK CITY, Utah — The protesting of racism and police brutality by American athletes started with W.N.B.A. players at a news conference in July 2016 and soon spread to the playing fields of the N.F.L. and the hardwood courts of the N.B.A. In less than five months, the Winter Games in Pyeongchang, South Korea, will present a far larger stage for demonstration: an Olympic podium.

Kehri Jones, an Olympic hopeful in bobsledding, was among those at an athlete summit here this week who said that athlete activism was something she had been thinking about and discussing with teammates as the Pyeongchang Games approach. The matter intensified last weekend after President Trump disparaged N.F.L. players who had chosen to kneel during the national anthem in protest of police violence.

“I am an African-American woman and my family is all African-American,” said Jones, who is from Fort Hood, Tex. “I worry about my family and my siblings and my father going out and ending up in some of these awful situations,” she added, speaking of police brutality.

“It’s a really fine line I’m walking because my dad is in the military and I want to represent our country well,” Jones continued. Her father is scheduled to be deployed during the Winter Games. “But I also want to represent all the social injustice that has been going on.”
