GOP lawmaker: Dems' obstruction slowing Benghazi probe

Responding to criticism that the investigation into the Benghazi attack has stretched on longer than the Watergate investigation, Rep. Mike Pompeo, R-Kan., said Sunday that the committee has been working for so long because of obstruction on the part of Democrats.

"What's taken us so long is Democrats on the committee and in this administration have played hide the ball," he said on NBC's "Meet the Press." "We would have been happy to move more quickly but we were met with obstruction all along the way."

Hillary Clinton is expected to testify this week before the House Select Committee on Benghazi.

Rep. Adam Schiff, D-Calif., said if Republicans were really looking to get to the bottom of the attack on the consulate that killed four Americans and ensure it never happens again, they would call witnesses other than Clinton and those tied to her, such as the defense secretary or CIA director at the time of the attack in 2012.

"The reason they haven't brought any of these people in ... is because they're not running for president," Schiff said.
