OXON HILL, Md. » The head of the National Rifle Association is attacking President Barack Obama’s call for mandatory background checks for gun owners.

The NRA’s Wayne LaPierre says those who favor mandatory background checks may be, quote, “insane.”

LaPierre says background checks won’t make schools safer. Instead, he says, the checks will let the government tax gun owners or take their weapons. He spoke to activists today at the Conservative Political Action Conference in suburban Washington.

Obama has called on Congress to tighten gun laws following the Connecticut school shooting that killed 26 children and educators. The president supports a series of reforms, including mandatory background checks and a renewal of the assault weapons ban.

Conservatives say they are increasingly confident Congress will reject any reforms.
