The monuments may be gone, but the conversation continues — this time on "60 Minutes." 

New Orleans mayor Mitch Landrieu will join CNN anchor Anderson Cooper at the location where the removed monuments are housed. An image promoting the show shows the pair standing in front of the statues of Robert E. Lee and P.G.T. Beauregard. 

“Really what these monuments were, were a lie,” Landrieu says in the interview, according to a release.

The future of the monument sites has been a topic of contention since the four — honoring the Battle of Liberty Place and Jefferson Davis as well as Lee and Beauregard — were removed in 2017.

The first three were removed at night, with the city citing safety concerns, while Lee was removed in the daylight. Lee's removal was also followed by a speech from Landrieu that thrust him onto the national stage, many citing his eloquence, and even into some presidential rumors. 

Landrieu this week revealed plans for three of the monument sites, with a public forum planned for ideas about the future of Lee Circle. 

An American flag will be placed at the site of the former Jefferson Davis monument, while the Beauregard pedestal will be removed. The site of the former Liberty Place monument will remain empty. 

The episode will air on CBS at 7 p.m. Sunday.
