CBS's Barry Petersen slanted in favor of dissenters agitating for the repeal of the Catholic Church's centuries-old practice of celibacy for priests on the March 10, 2013 edition of Sunday Morning. Petersen hyped how "many American Catholics wonder how long celibacy will be a part of today's Church, or perhaps, how soon it may become a fading tradition."

The correspondent also failed to mention that Bill Wisniewski, one of his talking heads, is a board member for a dissenting group headed by Sister Christine Schenk, who was also featured during his report.

Imagine you're getting ready to head to church one fine Sunday morning and on your television you hear a man say, "Let's give up on the Constitution."

Such actually happened when CBS News Sunday Morning aired a rather inflammatory commentary by a Georgetown University law professor teased by host Charles Osgood asking, "Is the U.S. Constitution truly worthy of the reverence in which most Americans hold it?" (video follows with transcript and commentary):

Once a day for 25 days, NewsBusters is showcasing the most egregious bias the Media Research Center has uncovered over the years — four quotes for each of the 25 years of the MRC, 100 quotes total — all leading up to our big 25th Anniversary Gala on September 27.

So far, we’ve published the worst quotes from 1988 through 1992 (you can check those out here). Today, the worst bias of 1993, including the Washington Post smearing Christian conservatives as "poor, uneducated and easy to command," Dan Rather fawning over Bill and Hillary Clinton, and Helen Thomas disavowing any tilt, saying she does not “know what a liberal bias is.” [Quotes and video below the jump.]

Charlie Rose did his best to avoid asking any tough questions during an interview of President Barack Obama and his wife Michelle that aired on Sunday's CBS Sunday Morning and Monday's CBS This Morning. Rose devoted over four straight minutes to the couple's summer vacation, family life, and marriage. He also touted the Democrat's ObamaCare law as "enormously successful," and wondered if it was his "proudest achievement in the first four years."

Rose, who hounded House Speaker John Boehner over Rep. Paul Ryan's budget plan during a April 2012 interview, harkened back to the 2008 Obama campaign and early presidency by showing off a 2009 issue of Newsweek with a picture of the President taking the oath of office. He then asked, "This was also a time of 'yes, we can'; hope and change. What happened to that, because that's not the narrative today?"

CBS's Allen Pizzey completely whitewashed the struggling European economy on CBS Sunday Morning to bash the Republican presidential candidates' attack on President Obama's economic policies. Pizzey zeroed-in on Germany's lower unemployment rate and cited left-leaning Professor James Walston, who claimed that "the candidates are dealing in caricatures of Europe that are about 90% wrong."

The journalist played clips from Newt Gingrich and Mitt Romney, who defended the U.S. Constitution and ripped "European socialism." He condescended in reply, "If you're a candidate who wants to move to the White House, why worry about details?" Pizzey also turned to a European woman who insulted the Republican candidates' intelligence: "I just hope that most Americans are just more intelligent than those politicians" [audio clips available here; video below the jump].
