Deaths, guns, whistle-blowers and the highest law officer in the land stonewalling a congressional investigation are the juicy ingredients of a story network news reporters would love to cover – if a Republican were in office. However, when Attorney General Eric Holder testified on Thursday (February 2) before a House oversight committee investigating Operation Fast and Furious, the news was completely ignored by NBC and ABC (there was one full story on Friday’s CBS This Morning). The virtual blackout of Holder’s testimony continues an overall trend of ABC and NBC burying one of the Obama administration’s biggest scandals, despite continual coverage by their competitors at CBS, CNN and Fox News.

MRC analysts reviewed the Big Three network evening and morning news shows and found that while CBS aired 29 stories and 1 brief on Fast and Furious, ABC aired only one brief on the June 15, 2011 edition of Good Morning America. That was still better than what NBC did on their morning and evening news programs, as the gunwalking story has never been mentioned on either NBC Nightly News or the Today show. NBC’s Miguel Almaguer, in a report primarily about a Mexican mother accusing border patrol agents of killing her 17-year old son as he tried to scale a wall, did note that “In December, Border Patrol Agent Brian Terry was killed in a shootout with bandits.” However, Almaguer never tied the Terry killing back to the gunwalking scandal.

On Tuesday's The Early Show, CBS's Katrina Zish filed a full report on the trend toward more women becoming gun enthusiasts.

Last October, The Early Show notably ran a report documenting public opposition to gun control.

Co-anchor Chris Wragge and substitute co-anchor Rebecca Jarvis set up Tuesday's report: (Video below)

In Thursday's interview with Sen. John McCain (R-Ariz.), Early Show co-host Chris Wragge asked if Republicans in Congress are basically helping President Obama get re-elected with their ongoing opposition to the Senate's two-month payroll tax cut extension plan.

"Are you essentially handing President Obama his re-election bid here by handling this the way the Republicans have handled this?" Wragge asked guest Senator McCain. The senator has been a noted critic of House Republicans in their refusal to vote for the Senate plan.

Former New York City police commissioner Bill Bratton brought his pro-gun control agenda into a segment about the FBI's latest crime statistics on Tuesday's Early Show on CBS, blaming the "the insanity of the lack of gun control laws in this country" for an increase in police deaths during 2011.

Anchor Erica Hill introduced Bratton as the "chairman of Kroll, a worldwide investigative company. He's also the former chief of police in Los Angeles, New York City, and Boston." During most of the segment, Hill and co-anchor Chris Wragge asked their guest for his take about the overall decrease in violent crime, according to the FBI statistics.

On Tuesday's Early Show, CBS's Cynthia Bowers let abortion advocates decry new pro-life legislation at the state level, barely letting supporters speak in her report. Bowers slanted by a three to one margin in the number of sound bites that she played from "abortion rights" supporters versus those from pro-lifers. She labeled Kansas Gov. Sam Brownback a "staunch abortion opponent," while giving no equivalent label to a pro-choicer.

The correspondent led the segment with a clip from an unidentified woman who aborted her unborn child who had been diagnosed with anencephaly, a disorder where most of the baby's brain fails to develop. She continued that the woman's obstetrician " of only three clinics in the entire state [of Kansas] that still performs abortions- access that could soon be cut even further."

CBS's Early Show on Wednesday boosted a claim by Democrats that a recent Mitt Romney ad takes a line from a 2008 speech by then-candidate Barack Obama out of context. However, CBS noted at that time that Obama was using that line to counter a McCain campaign ad which played up the Democrat's association with left-wing terrorist Bill Ayers.

Anchor Erica Hill raised the controversy over the Romney ad towards the end of a segment with political correspondent Jan Crawford about the most recent Republican presidential debate. After playing the relevant part of the commercial, which includes a clip of Obama stating that "if we keep talking about the economy, we're going to lose," Hill asked, "A lot of controversy over that ad, Jan. Why?"

CBS's Chris Wragge spotlighted a millionaire's bid to raise taxes on the rich on Thursday's Early Show, all the while omitting that his guest is a big money donor to liberal candidates like Al Franken and to Wragge didn't bring on any opponents of higher taxes, nor did he play sound bites from them. Instead, he played three clips from proponents, including former Clinton aide Robert Reich.

Wragge and co-anchor Erica Hill trumpeted the "so-called patriotic millionaires [who] are begging Congress to raise their taxes" as they teased the segment three different times before it began. Hill did mention once that "they also spoke with a critic who said if they want to pay more, then they should make a contribution on their own, instead of raising taxes on all millionaires."

On Monday's Early Show, CBS's Rebecca Jarvis wondered if Newt Gingrich would "have to play a little more take on the other GOP contenders to win the bid." Bob Schieffer replied cynically that Gingrich would "save his criticism for attacking the media, which is always the safe thing to do." Chris Wragge prompted the former Speaker to criticize Herman Cain and Rick Perry on Friday, but he didn't bite.

Jarvis brought on the Face The Nation host for his take on Republican presidential debate hosted by CBS and National Journal on Saturday. Near the end of the interview, the fill-in anchor raised how Gingrich was "gaining momentum" and that he "held true to this no real confrontation with the other candidates" during the debate. She then directed her "dirty" question to Schieffer.

Elaine Quijano continued CBS's consistently glowing coverage of the Occupy Wall Street movement on Wednesday's Early Show by spotlighting how two-thirds of Crosby, Stills, and Nash gave a concert for the protesters in New York City. Quijano played 12 clips from the concert and from the demonstrators, without once mentioning the growing examples of violence involving the left-leaning movement [audio clips available here; video below the jump].

Anchor Chris Wragge introduced the correspondent's report by noting only in passing how "anti-Wall Street protesters around the country are under growing pressure to go home...critics in several cities are saying they're just becoming a public nuisance." Co-anchor Erica Hill added that "here in New York City, demonstrators say they are in it, though, for the long haul- yes, even with winter coming. Correspondent Elaine Quijano takes a look at what the future holds for the protests."

On Friday's The Early Show, CBS correspondent Whit Johnson filed a report highlighting a recent Gallup poll finding a majority of Americans opposing new gun control laws at the highest rate ever recorded. After beginning the piece by highlighting a woman who just recently decided to become a gun owner for the first time in her life, Johnson detailed some of the poll's findings:

Thursday's Early Show on CBS provided free air time to Rep. Steve Israel of the Democratic Congressional Campaign Committee and three of his top candidates for the 2012 election. Correspondent Nancy Cordes trumpeted how the Democratic Party is "determined to bounce back from their big losses" to Republicans during the 2010 cycle and highlighted that the three were "running against Tea Party members."

Anchor Chris Wragge teased Cordes's report by touting how Democrats were "finding their own outsiders to run against the Washington status quo. We're going to talk to some of those new recruits, including a former astronaut and a former police chief, who they say with Congress more unpopular than ever, they've got a good chance to make the kind of change in Washington that they feel Washington needs."

On Thursday's Early Show, CBS's Chris Wragge bizarrely wondered if the dissatisfaction with the current GOP field of presidential candidates would give President Obama an edge: "Is this just primary politics, or does this make candidate Obama kind of lick his chops, thinking he's got a real advantage here?" Mr. Obama actually trails a generic Republican candidate in two recent polls.

Just moments before Wragge dropped his question, correspondent Jan Crawford had explained during a report that such dissatisfaction from primary voters wasn't unusual in either party from a historical perspective. Crawford cited the Democratic presidential fields in 1991 and 2003 as examples:
