Donald Trump is known to be obsessed with crowd size, but any efforts to secure a number of attendees for the inauguration will be complicated by the event being moved inside the Capitol building due to cold weather.
About 250,000 spectators were expected to descend on downtown Washington to attend the event, but the area from which they were scheduled to watch was closed. Inauguration parties usually attract hundreds of thousands of people without tickets to the National Mall, but this year's turnout will be jeopardized by the weather.
The presidential parade, which normally travels down Pennsylvania Avenue from the Capitol to the White House, was moved to Capital One Arena, which seats 20,000 people.
In 2017, Trump was angry after photos showed that fewer people were at the mall for his first inauguration than for Barack Obama in 2009.
An estimated 250,000 to 600,000 people attended Trump's first inauguration, according to PolitiFact. Obama's inauguration brought an estimated 1.8 million (2009) and 1 million (2013) to the National Mall, while George W. Bush's inauguration attracted 300,000 (2001) and 400,000 (2005).
