South Bend, Ind., Mayor Pete Buttigieg is being slammed – and also defended – after a 2017 Instagram post of him at a Holocaust memorial in Berlin, with the caption "This guy," resurfaced Sunday on Twitter.

The Democratic presidential candidate’s husband, Chasten Buttigieg, posted the photo of Buttigieg at what appeared to be the Memorial to the Murdered Jews of Europe, in Germany's capital.

Users on Twitter called the photo and caption “tone-deaf,” “inappropriate, “tasteless” and “disrespectful.”

"Honestly, I think it's more the, uh, caption than the picture itself," one Twitter user wrote. "Something about implying how dreamy your husband is with a Holocaust memorial as the backdrop comes off as a bit tone-deaf, so it's actually a decent microcosm of the Buttigieg campaign."

BUTTIGIEG SLAMMED BY TRUMP CAMPAIGN'S BLACK OUTREACH INITIATIVE: 'WHAT HAVE YOU DONE FOR THE BLACK COMMUNITY?'

NBC reporter Ben Kesslen first tweeted a screenshot of the post, writing “is this....at the holocaust memorial in berlin....” on Sunday.

Although considered disrespectful, tourists frequently take photos at Holocaust memorials and concentration camps like Auschwitz.

Not everyone was offended by the photo. Some Twitter users saw the picture as harmless and the criticism politically motivated.

"He looks more respectful than most people who visit the memorial nowadays," one user wrote. "Anyone who's been there can attest."

"As someone who lost relatives in the Holocaust, including my great grandparents, your using this to smear Pete is absolutely appalling to me. Try a little self-reflection," another user commented on Kesslen's post.
