FOX News has done a fact check on the Ryan budget and concludes:
Here are a few little-known facts about Paul Ryan's supposedly slash-and-burn budget plan.
Government spending increases almost every year over the next decade.
Tax and other revenue rises year after year.
The 10-year deficit is still $3 trillion.
The fact that Ryan's spending plans grow the federal budget over the long term is one that could easily be lost in the political melee underway in the wake of his selection as Mitt Romney's running mate.
To be sure, Ryan is proposing major changes to Medicare and taxation that Democrats see as problematic.
But claims that Ryan is slashing spending don't quite square with the numbers.
