Audit Says Border Fence Will Cost $6.5 Billion To Maintain

The border fence is going to cost more than $6.5 billion to maintain over the next 20 years. That's the price tag a government audit is estimating. That's in addition to the $2.5 billion that's been spent on more than 600 miles of construction.

The report says the Obama administration does not have a way to evaluate whether the investment has helped control illegal immigration.
