NYT article from 1989:
"Sirhan Sirhan, in his first television interview, said he felt betrayed by Senator Robert . Kennedy's support for Israel in the 1967 Arab-Israeli war and said he killed Mr. Kennedy out of concern for the Palestinians.
''My only connection with Robert Kennedy was his sole support of Israel and his deliberate attempt to send those 50 bombers to Israel to obviously do harm to the Palestinians,'' he said.
Mr. Sirhan, 44 years old, said that when he killed Mr. Kennedy, who was then the leading candidate for the Democratic Presidential nomination, ''I was not doing it out of personal malice toward the man, but out of concern for other people.''
Mr. Kennedy ''was my hero,'' Mr. Sirhan said. ''He was my champion.''
