Republican insists that hearings on Benghazi aren't politically motivated

House Oversight Committee chair Darrell Issa insisted Sunday that Republicans had no agenda to "target" Democrats in the Obama administration for their handling of the attack of the Benghazi mission in Libya while slamming a lack of "accountability" for the tragedy.

"Hillary Clinton is not a target. President Obama is not a target," said Issa (R-Calif.) on NBC's "Meet the Press."

"The target is, 'How did we fail in three different ways? Fail to heed the warning of an impending attack, fail to respond properly during the attack?" he said.

Issa said the administration also failed "to get the truth to the American people in a timely fashion," about what he called "a terrorist attack from the get go" that resulted in the deaths of four people, including U.S. Ambassador J. Christopher Stevens.

Later in the program, California Sen. Dianne Feinstein, a Democrat, expressed skepticism that the hearings on the Benghazi were not politically motivated.

"When Hillary Clinton's name is mentioned 32 times in a hearing, then the point of the hearing is to discredit the secretary of state, who has very high popularity and may well be a candidate for president," Feinstein said.
