American gold medalist fencer Race Imboden knelt as the national anthem played Friday at the Pan American Games in Lima, Peru, to protest racism, gun control, mistreatment of immigrants and President Donald Trump. “We must call for change,” he tweeted afterward along with a photo. “This week I am honored to represent Team USA at the Pan Am Games, taking home Gold and Bronze. My pride however has been cut short by the multiple shortcomings of the country I hold so dear to my heart. Racism, Gun Control, mistreatment of immigrants, and a president who spreads hate are at the top of a long list. “I chose to (sacrifice) my moment today at the top of the podium to call attention to issues that I believe need to be addressed. I encourage others to please use your platforms for empowerment and change,” he said.
