WASHINGTON (AP) — Should veterans deemed too mentally incompetent to handle their own financial affairs be prevented from buying a gun?

The issue, for a time last week, threatened to become the biggest sticking point in a $631 billion defense bill for reshaping a military that is disengaging from a decade of warfare.

Sen. Tom Coburn, R-Okla., sought to amend the bill to stop the Veterans Affairs Department from putting the names of veterans deemed too mentally incompetent to handle their finances into the National Instant Criminal Background Check System, which prohibits them from buying or owning firearms.
