On Independence Day in the United States, free-agent quarterback Colin Kaepernick posted a video on social media of his trip to Ghana, where he traveled to find his "personal independence."

He posted the video on Twitter with a message asking, "How can we truly celebrate independence on a day that intentionally robbed our ancestors of theirs?"

How can we truly celebrate independence on a day that intentionally robbed our ancestors of theirs? To find my independence I went home. pic.twitter.com/hniYGJeLxG — Colin Kaepernick (@Kaepernick7) July 4, 2017

He posted a longer message on Instagram with the video, explaining why he was interested in traveling to Ghana. In order to find his personal independence, he "had to find out where my ancestors came from," and tracing his ancestral roots led him to Ghana.

Kaepernick has used his social media platforms to support social causes but has remained silent on his football career. Many NFL players have said they believe Kaepernick is being "blackballed" by NFL teams because of his decision to kneel during the national anthem last season.
