The "Pledge to America" only calls for reductions to non-security discretionary programs; that means agencies like the Department of Veterans Affairs, Department of Homeland Security, and Defense Department would be exempt. The GOP's plan would cut non-security discretionary funding—the roughly one-third of government spending controlled by Congress, which excludes programs like Social Security and Medicare—by nearly 22 percent, shaving $105 billion off of President Obama's $483 billion 2011 budget proposal.
