President-elect Joe Biden’s transition team appeared to delete an old campaign ad that criticized Pete Buttigieg for his lack of experience — after the former Indiana mayor was nominated to serve as transportation secretary, according to a report.

The ad ran in February before the New Hampshire primary election and contrasted Biden’s long career as a senator and as vice president in the Obama administration with Buttigieg’s time as mayor of South Bend, Ind. — a city of 100,000, Fox News reported.

“We’re electing a president. What you’ve done matters,” the narrator in the ad said.

The ad ran on Facebook and YouTube on Feb. 8 and came days after Buttigieg won the Iowa caucuses and Biden finished in fourth place.

Buttigieg’s campaign at the time hit back, calling it “classic Washington-style” politics.

The YouTube link now says the video is unavailable and has been “removed by the uploader.”

Speaking on Wednesday in Wilmington, Del., Biden struck a much different tone, calling his former rival “one of the smartest people you’ll ever meet and one of the most humble.”

“A mayor from the heartland, a management expert, a policy wonk with a big heart, a veteran, lieutenant in the United States Navy Reserve, an intelligence officer deployed to Afghanistan while he was mayor. A new voice with new ideas, determined to move past old politics,” Biden gushed.

Buttigieg dropped out of the presidential race March 1 after finishing poorly in the South Carolina primary.

He endorsed Biden the next day.

South Bend’s transit system carries about 4,300 people per day and consists of 66 buses, according to a 2019 report from the Indiana Department of Transportation.
