WASHINGTON (AP) — House Speaker John Boehner declared Friday he would create a select committee to investigate the Benghazi attack, providing Republicans with a high-profile forum to target the Obama administration’s credibility ahead of crucial midterm elections.

Boehner said U.S. officials misled the American people after the Sept. 11, 2012, assault on the U.S. diplomatic outpost in Libya that killed Ambassador Chris Stevens and three other Americans. He said emails released this week showed the White House has withheld documents from congressional investigators and asked, “What else about Benghazi is the Obama administration still hiding from the American people?”
