However, Watson, who is black, said he felt it was important to stand with the group to support freedom of speech. He walked side-by-side rally organizer Jason Kessler as the group marched from Foggy Bottom to Lafayette Park.

"Everybody has a right to speech,” Watson told journalists. "I wouldn’t be here if my man was a white supremacist.”

As he spoke the chants of counter-protesters echoed from across the park as hundreds decried the gathering of various groups, including some white supremacist and white nationalist members.

Kessler, who said he is not a white supremacist, said he agreed with Watson’s sentiment adding, “White people deserve to stand up for their rights like other people are able to do.”
