Monday’s ceremony marks only the second inauguration on Martin Luther King Jr. Day. After the swearing-in ceremony, Trump said he plans to sign nearly 100 executive orders on his first day. A desk was set up at Capitol One Arena where NewsNation’s Libbey Dean reports he will sign those orders in front of an audience Monday evening.
