How much will all the inaugural events cost? It's hard to say.
While most events that occur in the capital have a hard-and-fast budget, the inauguration's many moving parts, safety concerns and large geographic reach make it hard to quantify – especially before the main event.
In 2009, ABC reported the total cost of Obama's first inauguration was $170 million. While incumbent presidents historically spend less on a second inauguration, it's unclear what the total bill will be this time around. Analysis of some of the known appropriations so far puts the total at $13.637 million, but it will no doubt be a much larger price tag when everything is accounted for.
