The evening news shows on the broadcast networks these days arent always fixated on politics. They often lead their half-hours with frightening weather footage, and turn to Washington about 10 minutes later. But ABC, CBS and NBC can still determinewhat political scandals should be considered important, and what scandals should be buried and not acknowledged as scandals.The networks blatantly demonstrate their partisanship by treating Republican scandals as urgent matters loaded with historical weight, and dismissing Democrat scandals as either nonexistent or as desperately partisan misinformation.When Democrat and then-House Speaker Nancy Pelosi stacked a "special committee" on the January 6 riot with only two personally picked Republicans who would obey all of her commands, that was "historic" and nonpartisan. All of its hearings were aired live on the broadcast networks every minute, even in prime time. When Republican House Oversight Committee Chairman James Comer investigates anything about former President Joe Biden and the Democrats, these networks act like all of their Capitol Hill reporters were laid off.REP. JAMES COMER MOCKS NBC STORY EQUATING HIS DIGITAL SIGNATURE WITH BIDEN'S AUTOPEN SCANDALOne major scandal of historical import is Bidens mental decline throughout his presidency, and especially at the end, as Democrats refused to consider any primary opponents, trying to push him into another four incapable years.In May, an online national I&I/TIPP Poll found 58% of those surveyed were in favor of hearings (or even criminal proceedings) on the Biden-decline scandal, and only 30% picked "do nothing, its just politics as usual." All of the so-called scandal cops at the networks are in the minority.The networks failed to move on Monday morning when The New York Times published an eye-opening front-page story. The headline was bland "Biden Says Autopen Clemencies Were All His" but within, you could see that Biden was letting his staff make decisions for him. NBC offered 34 seconds on Monday night. The others did not.BROADCAST BIAS: HOW NETWORKS BURIED A BOMBSHELL SENATE HEARING ON BIDEN'S MENTAL FITNESSEarly on Monday,NBCNews.compublished a ludicrous article with the Democrat spin that Rep. Comer has used digital signatures in committee correspondence as if thats anything like a president being unaware if he pardoned a cocaine dealer. That story was so lame that NBC didnt even put it on "Today" or "Nightly News." It was just MSNBC bait.On Wednesday, Comers committee dragged in subpoenaed top Jill Biden aide Anthony Bernal. Hes a major figure in "Original Sin," the Alex Thompson-Jake Tapper book on hiding Bidens cognitive decline. "Bidens aides would say that she was one of the most powerful First Ladies in history, and as a result he became one of the most influential people in the White House," wrote Thompson and Tapper. They touted Bernal as the "loyalty police" and one of the "protectors of the myth."Bernal is still loyal: he took the Fifth Amendment. "Well, unfortunately, that was quick," said Comer after the deposition ended. "I believe the American people are concerned. Theyre concerned that there were people making decisions in the White House that were not only unelected but no one to this day knows who they were."BROADCAST BIAS: THE NETWORKS ADORED TRUMP 'TELL ALL' BOOKS, BUT DOWNPLAY BOOKS WITH BIDEN SCOOPSABC, CBS and NBC failed to devote one second to this story. If it pleases President Donald Trump, its not getting touched. Taxpayer-funded PBS and NPR had no segment. (Fun fact: neither did Jake Tapper on his CNN show that day.) These networks didnt offer that judgment when Trump aides took the Fifth before the Pelosi-picked panel on January 6. That showed rotten contempt for the public!CLICK HERE FOR MORE FOX NEWS OPINIONBernal was not alone: on July 9, Bidens personal doctor Kevin OConnor repeatedly took the Fifth. In that case, "NBC Nightly News" offered a story. The other networks did nothing.This week, the broadcast networks properly devoted stories to Trumps new diagnosis of a "chronic veinous insufficiency," but that is a routine diagnosis for older people. It in no way compromises his capacity to be president, unlike Bidens growing enfeeblement.BROADCAST BIAS: NETWORKS' TAKE ON TRUMPS 100 DAYS WAS 100% SHOCKING, 0% SURPRISINGOf course, there was a Trump scandal to push at these networks this week: a fight between Trump supporters over what would be released by the Justice Department about the late child-sex trafficker Jeffrey Epstein. Among them, the Big Three evening newscasts devoted 20 minutes and eight seconds to Trumps Epstein problems from Monday through Thursday, more than half of it (11 minutes, 43 seconds) on ABC.ABCs Rachel Scott performed the classic spin at the end of her story on Thursday: "And as much as the president wants to turn the page, behind the scenes, this is consuming a lot of time at the White House. His advisers [are] meeting about this, trying to figure a way to move past it, but many Republicans [are] making it clear this is not going away."Scandals are "not going away" when the liberal networks want to inflict headaches on the Republicans. With Democrat scandals, they cant "go away" when they never arrived.CLICK HERE TO READ MORE FROM TIM GRAHAM
