Washington — Common Cause, the public-interest lobby, has called on President Reagan to launch a White House inquiry into alleged gifts from Japanese journalists to national-security adviser Richard V. Allen, Monitor correspondent Richard J. Cattani reports.
''In any administration, the White House is responsible for setting the highest possible standards of conduct for those who serve in the executive branch,'' said Common Cause president Fred Wertheimer in a letter to White House Chief of Staff James A. Baker.
The White House has repeatedly said the Justice Department inquiry satisfies the needs of the Allen case.
In a related development, Sen. Charles H. Percy (R) of Illinois, chairman of the Senate Foreign Relations Committee, said the Allen allegations, unless cleared up, will cost Allen his credibility on Capitol Hill. He suggested a special prosecutor may have to be appointed.
