Today marks the one-year anniversary of the attack on the U.S. embassy in Benghazi that left Ambassador Chris Stevens and three other Americans dead. The attack sent the Obama administration scrambling for a cover story that the Big Three broadcast networks initially bought and were slow to unravel.

A similar pattern has emerged in 2013. As new information about the administration's actions before and after the attacks has been revealed through congressional testimony, whistleblowers, and eyewitnesses, the Big Three networks have responded by breezing past, ignoring, or spinning politically damaging bombshells. Read the MRC's full report here.

From praising Hillary's January testimony on Benghazi as a "fiery" "valedictory" to ignoring accusations of witness intimidation, the networks have, for the most part, operated as an arm of the White House PR machine.

The liberal "news" media's refusal to cover the Benghazi story exposes just how corrupt they have become. Consider some of the stories that have surfaced but have been distorted or, worse, completely ignored by the willfully dishonest media:

Unfortunately, the leftist media have punted on each of these stories. They refuse to investigate as the Obama administration dodges the truth and sidesteps accountability.

This reeks of a cover-up.

If ABC, CBS, NBC, The Washington Post, and The New York Times refuse to ask the tough questions to get to the TRUTH, then they no longer serve any purpose. If the liberal media sit on evidence to protect Barack Obama as well as their anointed 2016 presidential contender, Hillary Clinton, then they are equally complicit in the Benghazi cover-up.

If the liberal media need motivation to investigate Benghazi, perhaps they should pretend Barack Obama and Hillary Clinton are Republicans.

The media, which are so invested in their left-wing agenda, refuse to do their job and hold the Obama administration accountable. It's time to turn up the heat and demand answers from the leftist media.

You can stand with the Media Research Center in our pursuit of the truth. With your help, we will expose the liberal media's censorship of the Benghazi story and demand they turn up the pressure on the Obama administration.

The media have an obligation to the victims, their families, and the American people to investigate Benghazi until the truth is known. Stand with the MRC today and insist that the media probe for the answers we want and deserve.

Thank you for standing with the Media Research Center as we pursue the truth about Benghazi. The victims' families and the American people deserve to know what happened that fateful night of September 11, 2012. With your help, we can pressure the liberal media to do their job and begin asking the hard-hitting questions that will lead to the truth.
