Sen. Hillary Rodham Clinton's campaign accused Sen. Barack Obama's campaign of fanning a controversy over her describing the assassination of Robert F. Kennedy late in the 1968 Democratic primary as one reason she is continuing to run for the presidency. "The Obama campaign ... tried to take these words out of context," Clinton campaign chairman Terence R. McAuliffe said on "Fox News Sunday." "She was making a point merely about the time line."The issue is particularly sensitive given longstanding concerns about Obama's safety as a presidential candidate. (He first received Secret Service protection last May.) The Obama campaign called Clinton's words unfortunate and circulated a TV commentary criticizing them, although Obama himself said Saturday that he took Clinton at her word that she meant no harm.
