(CNN) - Senior Obama adviser David Plouffe on Sunday argued the politicization of the attack in Benghazi, Libya "has been unprecedented" and invoked George W. Bush to make his case.
Plouffe said when terrorists bombed the U.S.S. Cole in October 2000 - just weeks before the presidential election - then-Republican candidate Bush said "we need to speak with one voice" rather than criticize the Clinton administration.

"And really for that entire campaign, President Bush and Dick Cheney said 'we need to speak with one voice, we need to find out what happened here', and I do think the politicization has been unprecedented," Plouffe said on NBC's "Meet the Press."
Republicans, including presidential nominee Mitt Romney, have harshly criticized the Obama administration's handling of the September 11, 2012 attack on the U.S. consulate in Libya, which left U.S. Ambassador Chris Stevens and three other Americans dead.
They've questioned whether the administration provided adequate security ahead of the incident and whether officials misled the public about what led to the attack. Romney has said what occurred in Libya is evidence Obama's policies in the Mideast are unraveling.
On Sunday, Plouffe insisted the administration has been forthcoming about the attack and said the president is committed to making sure the country understands what happened.
When asked if the administration is deliberately waiting until after Tuesday's election to release the findings of its investigation, Plouffe said, "Absolutely not."
