What to watch at the inauguration tomorrow

Donald Trump's inauguration as the country's 47th president was expected to be an extravagant break from tradition -- before it got moved indoors due to cold weather.

There will still be well-known performers, influential billionaires as guests and foreign heads of state. Unlike his first inauguration eight years ago, Trump will be welcomed back to office by business titans and global leaders, groups that often shunned him in his first term.

The inauguration is moving indoors. Here's what to know about the changed plans

Sub-freezing temperatures forecast for Monday in Washington mean President-elect Donald Trump will take the oath of office from inside the Capitol Rotunda. Almost everyone visiting Washington won't be able to see the ceremony in person.

It will be the first time in 40 years that the swearing-in won't take place on the Capitol steps. Plans are underway to accommodate some attendees at the city's pro basketball and hockey arena.
