"The Republican Benghazi report seems like a conspiracy theory on steroids — bringing back long-debunked allegations with no credible evidence whatsoever," the release stated.
Earlier on Tuesday, Republicans on the Benghazi committee released a report probing the 2012 attack, which killed US Ambassador Christopher Stevens and three other Americans.
"Republicans promised a process and report that was fair and bipartisan, but this is exactly the opposite," the release claimed.
Continuing controversy over the 2012 terrorist attack in Benghazi reflects the sharp divide between Republicans and Democrats in the US Congress. Republicans accuse the Obama administration of covering up its incompetent response to the attacks, while Democrats view the Benghazi Committee’s work as political theater intended to embarrass the administration.
