A crowd was told to redo its applause after President Biden showed up late to a Christmas tree lighting.  

The president and first lady were introduced at the Christmas tree lighting ceremony by LL Cool J, but the crowd waited nearly two minutes for the couple to come out. 

A video shows the rapper introducing the pair as music plays. As the crowd stands up, however, the president and first lady are nowhere in sight.

His speech ended with optimism for the future. 

"And as we look out across the country with the promise of a new year ahead, we know this: We are a great nation because [of] you — the American people," the president said. "You are a good people. And because of you, we will never be more optimistic about the future. You've made me so optimistic I can't — I tell you what ... we have so much ahead of us."
