Nikki Haley, the former governor of South Carolina, had a go at Vice President Kamala Harris on Sunday over Harris' well-wishes for the holiday weekend.

Harris shared a tweet on Saturday with a photo of herself and the message "enjoy the long weekend."

Haley, who served as President Donald Trump's ambassador to the United Nations, retweeted it on Sunday afternoon and wrote, "Unprofessional and unfit."

It wasn't clear exactly what Haley didn't like about the tweet. But some Twitter users expressed disapproval that Harris had tweeted about the long weekend instead of what Memorial Day is about.

Memorial Day takes place on the last Monday of May to honor and mourn United States military personnel who died in the line of duty.

Harris tweeted on Sunday morning, hours before Haley's criticism, about the meaning of the national holiday.

"Throughout our history our service men and women have risked everything to defend our freedoms and our country," Harris said. "As we prepare to honor them on Memorial Day, we remember their service and their sacrifice."

For her part, Haley had not tweeted about Memorial Day as of Sunday night.

Haley, a Republican, is widely thought to be a likely 2024 presidential candidate. She has said that if Trump were to run she would support him, despite criticizing him after the Capitol riot. "He went down a path he shouldn't have, and we shouldn't have followed him, and we shouldn't have listened to him," she told Politico in February. "And we can't let that ever happen again."
