ABC reports tonight: “Republicans accuse the White House of playing politics. But the White House says it is canceling the tours because sequester spending cuts have sliced $84 million out of the Secret Service’s $1.6 billion budget. And they are the ones who secure the tours. They wouldn’t say how much this saves, so we did some math. Tours are open 20 hours a week and use 30 uniformed Secret Service officers at about $30 an hour. Total saved? Approximately $18,000 a week.” …

Assuming ABC’s per-week estimate is correct, if you’re looking over an entire fiscal year, cancelling the tours saves about $1 million — or two-thirds of a thousandth (.0625 percent) of the entire Secret Service’s annual budget, and leaves about 98.5 percent of the cuts to the agency’s budget to fall elsewhere.
