The office of North Carolina congressman Howard Coble, who came under fire for comments he made last week approving the wartime internment of Japanese-Americans, has defended his position.

"It was both for national security and for (their) protection," a spokesperson at the Washington office of North Carolina congressman Howard Coble said Friday.

Coble, a Republican member of the House of Representatives, made the remarks Tuesday on a call-in radio show in Greensboro, North Carolina.

"In light of the threat to our national security, the fear that the west coast could potentially have been invaded, you know he (Coble) could understand how (President Franklin D.) Roosevelt arrived at his decision," the spokesperson said.
