Democratic Minnesota Rep. Keith Ellison, the deputy chair of the Democratic National Committee (DNC), recently posed for a picture with a woman holding a sign calling America “stolen land.”

“No human being is illegal on stolen land,” read the woman’s sign. Ellison posed for the picture, which was shared on Instagram, at an anti-Trump “Rise and Resist” march on June 20.

The congressman has a history of endorsing fringe political candidates and messages.

Ellison was caught on video wearing a T-shirt in May that read, “yo no creo en fronteras,” which translates to: “I don’t believe in borders.”

Ellison is vacating his seat in Congress in order to run for attorney general of Minnesota, although he will remain the DNC’s number-two official.
