Oprah posts on Instagram after dinner with Mayor Lori Lightfoot

An Instagram post by Oprah Winfrey is generating a lot of buzz.

The post shows Winfrey with Chicago Mayor Lori Lightfoot and her wife Amy.

In the post Oprah wrote, "Look who came for dinner @chicagosmayor and wife Amy. Our first time meeting. #sweethomechicago."

Mayor Lightfoot said the dinner was last Thursday at Oprah's California home. Dinner included beef, roasted chicken and vegetables.

"It was great...she's a tremendous person," Lightfoot said.

Last month, Lightfoot became Chicago's first African-American woman and first openly gay mayor.
