A spokesman for Ellison has not yet returned an email inquiring whether the congressman endorses the sign’s open borders message.

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.
