Holder defends self, vows not to quit
Draws fire from GOP on security, civil rights issues
For nearly three years, Republicans have attacked Attorney General Eric H. Holder Jr. on national security and civil rights issues. For months, they have criticized him over a gun-trafficking investigation gone awry, with dozens of leaders calling for his resignation. More than 75 members of Congress co-sponsored a House resolution last week expressing “no confidence’’ in his leadership. The intensifying heat on Holder comes as the Justice Department is stepping into some of the most politically divisive social issues of the day.
