'It feels great!' - President Biden enters WH

After taking the oath of office and a brief dash to shake some hands, Biden made it safely to the White House in a barricaded city guarded by more than 25,000 troops and devoid of the hundreds of thousands of spectators who normally throng to the quadrennial ritual.

The unprecedented precautions ensured the new U.S. president and Vice President Kamala Harris took office free of incident in a ceremony outside the U.S. Capitol, two weeks to the day after a mob attacked the building in a failed attempt to keep Congress from certifying their victory.
