While the NFL world continues to debate whether Colin Kaepernick remains a free agent because of his national anthem protests, the quarterback is focused on learning more about his heritage.

Kaepernick – who’s of mixed race and was raised by adoptive parents in Milwaukee – posted a clip Tuesday of his visit to Ghana, along with a caption that takes issue with the Fourth of July celebrations in the U.S.

Kaepernick’s biological father’s ancestors are from Ghana and Nigeria, which the 29-year-old discovered last year using a DNA test.
