CNN, in a report on the Centers for Disease Control’s finding that the teen birth rate increased in 2006, focused attention on what liberals surmise is a partial cause of the increase - President Bush’s advocacy of abstinence-only sex education. CNN correspondent Mary Snow, in her introduction to her report, noted that, "no one is saying for certain whether the rise in teen pregnancy is in fact a trend, but it is bringing attention to abstinence-only programs, and the roughly $176 million the federal government spends on them each year."

The report, which aired during the 4 pm Eastern hour of Thursday’s "The Situation Room," featured three sound bites from both sides of the debate. Two came from Cecile Richards, the president of Planned Parenthood, whose political leanings are never mentioned. The third came from Robert Rector of The Heritage Foundation, which is described as a "conservative think tank."
