President Donald Trump celebrated with an estimated 20,000 supporters for an indoor inaugural parade Monday inside Capital One Arena, after being sworn in as the 47th president of the United States.

Donald Trump will be sworn in as the 47th president of the United States on Monday at an inauguration ceremony that has been scaled back due to a forecast of severe cold weather in the nation's capital.

Former Vice President Mike Pence's entrance into President Donald Trump's inauguration was met with boos from Capital One Arena, where thousands of Trump supporters gathered ahead of the inaugural parade on Monday.
