David Daleiden became an anti-abortion activist back in high school in Davis, California, learning tactics from his elders and helping mobilize his peers. In college, he co-wrote an article with a professor depicting self-doubt among some abortion providers.
Now, as he turns 27, Daleiden has established himself as one of the most polarizing figures in America's abortion debate.
The anti-abortion movement views him as a hero for producing undercover videos seeking to implicate Planned Parenthood in illegalities related to the handling of fetal tissue. Abortion rights supporters see him as a villain, contending he used deceptive and illegal tactics to infiltrate locations where the videos were made.
The praise and the invective intensified after Monday's announcement in Houston that a grand jury had indicted Daleiden and one of his colleagues.
