President Trump gave a rousing speech to tens of thousands of Boy Scouts on Monday night at the National Boy Scout Jamboree in West Virginia, where he took a shot at President Barack Obama.

“You are the young people of character, integrity who will serve as leaders in our communities and uphold the sacred values of our nation,” Trump said.

Trump is the eighth president to attend the national event, according to ABC News. He took a jab at his predecessor for not attending.

“By the way, just a question,” Trump asked. “Did President Obama ever come to a Jamboree?”

The Boy Scouts then booed the former president and chanted, “We love Trump.”

Trump also regaled them with the story of how he won the 2016 presidential election.

“You remember that incredible night with the maps,” Trump said. “What we did in all fairness is an unbelievable tribute to you and all the millions and millions that came out to make America great again.”
