Aides to John McCain charge that the Los Angeles Times is suppressing a video of a 2003 banquet showing opponent Barack Obama praising a Palestinian activist.
The Times countered that its promise to a source bars the newspaper from posting the video that allegedly shows the Democratic presidential nominee praising Palestinian activist Rashid Khalidi at the banquet.
The newspaper reported Wednesday it first wrote about the video in an April article about Obama's ties with Palestinians and Jews while involved in Chicago politics. The report provided a description of the tape.
