Silently standing before reporters, Jenkins responded to questions by holding up a series of signs pointing out player community work and various examples of social inequality.
Jenkins, a co-founder of the Players Coalition, criticized the decision by the White House to cancel Tuesday's previously schedule Super Bowl LII celebration.
"It's hard to meet with people who don't agree with you and to have tough conversations about uncomfortable race-related issues and how to make positive change," Jenkins wrote on Twitter. "It takes courage to stand up for the TRUTH even if it's not a popular one."
Last month, Jenkins and several other NFL players hosted a forum in Oakland, California, to address criminal justice reform concerns -- one of at least four forums the Players Coalition plans to host on the issue.
In addition to meeting with NFL team owners and league officials to address concerns involving social inequality issues affecting players, members of the Players Coalition have gone on police ride-alongs, met with legislators on Capitol Hill and visited with community leaders to address issues affecting people across the country.
