what action taken by the US government during World War II violated the constitutional rights of some citizens

The question is incomplete. The options to this question are the following:

Tapping phones of suspected communists

Internment of Japanese citizens in camps

Preventing newscasts from showing casualties

Arresting peaceful protesters

Answer:

Internment of Japanese citizens in camps

Explanation:

After the Pearl Harbor attack on December 7, 1941, American public opinion turned against Japan, and people began to distrust Japanese Americans living in the country. A few months later, the U. S. President enacted Executive Order 9066, which detained and forcibly placed about 110,000 Japanese Americans in internment camps to guarantee the U. S. national security.

Such governmental action, however, was highly controversial as it was deemed to violate Japanese American's liberties and right of having due process of law, and a grand jury before being held to answer for a crime, as guaranteed under the Fifth Amendment.

The correct answer is the internment of Japanese-American citizens.

The United States government decided that Japanese-American citizens were a security threat and they put them into internment camps.
