‘Unite the Right' emails reveal potential speakers include former KKK grand wizard David Duke

Emails detailing plans for the "Unite the Right" rally in D.C. reveal potential featured speakers for the event include the former leader of the Klu Klux Klan.

Emails obtained through the Freedom of Information Act between organizers for the white nationalist event and National Park Service reveal among the potential speakers at the rally include former grand wizard of the KKK David Duke, who made headlines in 2016 when he signed up to run for the U.S. Senate in Louisiana, and neo-Nazi and Holocaust denier Patrick Little.

Organizers of the event have not officially confirmed a list of speakers for the rally set to be held on Sunday. The rally falls on the one-year anniversary of the Unite the Right rally in Charlottesville that turned violent and left one counterprotester dead.

Sunday's Unite the Right rally is set to be held at Lafayette Park near the White House and National Park Service said it has received four other permit requests for counterprotests that will happen at the same time nearby.

National Park Service notes that the Unite the Right rally's permit and the four permits for counterprotests have not yet been approved, but it's not uncommon to have permits approved at the last second. For reference, the March for Our Lives permit was issued five days before the rally and President Donald Trump's inauguration permits were issued the day before set up began.

"The permit will be issued when we have all the information necessary to ensure public safety and the protection of park resources. Not at all unusual for an event this complex to go up to last few days before the permit is issued. A lot of moving parts need to come together," Mike Litterest with National Park Service explained.

According to Unite the Right rally's website, marchers plan to meet at the Vienna Metro station and then they will convene at the Foggy Bottom Metro station where they will be escorted by law enforcement as they make their way down to Lafayette Park for a 5:30 p.m. rally.

Recently, Metro said it will not provide private trains to transport the white nationalists after reports they were considering it sparked outrage on social media.

Authorities said the current plan is to keep the white nationalists and the counterprotesters completely separated from each other on Sunday.
