PHILADELPHIA (CBS) — Philadelphia Mayor Jim Kenney is apologizing after a photo of him dining at a restaurant indoors in Maryland went viral. The photo made its rounds on social media Sunday with heavy criticism directed at Kenney as restaurants and bars in Philadelphia remain closed inside to customers.

“I know some are upset that I dined indoors at a restaurant in Maryland yesterday,” Kenney tweeted Monday. “I felt the risk was low because the county I visited has had fewer than 800 COVID-19 cases, compared to over 33,000 cases in Philadelphia. Restaurant owners are among the hardest hit by the pandemic. I’m sorry if my decision hurt those who’ve worked to keep their businesses going under difficult circumstances. Looking forward to reopening indoor dining soon and visiting my favorite spots.”
