— -- Today Donald Trump was sworn in as 45th president of the United States.

Of course, 16-year-old Jackie Evancho was there to sing the national anthem after Trump was sworn in and addressed the crowd.

"We are ready. Proud to be an American! #Trump #Inauguration," he wrote in a picture with his wife.

Fox News interviewed "Duck Dynasty" star Willie Robertson at the event, who said, "I was happy to be a part of this early, but there's a lot of people on board now, that's for sure."

Robertson's wife Korie attended events last night with her husband and took a photo with country star Tanya Tucker.

Comedian Chonda Pierce is to headline another inauguration event and posted photos of herself meeting fans in D.C.

After the events of today and tonight are finished, the Women’s March on Washington and other events not connected to the inauguration will take place Saturday in Washington, D.C., and across the country.

In addition to the main march in Washington, D.C., more than 150 other sister marches are expected nationwide on Saturday, many of them led by other celebrities.
