Yet another radical endorser has been added to the website of Texas Gov. Rick Perry’s The Response prayer rally: Rob Schenck of Faith And Action. During the 1992 presidential campaign, Schenck was arrested along with Randall Terry “after thrusting a container with a 19-week-old fetus at presidential candidate Bill Clinton,” and four years later told President Clinton “God will hold you to account, Mr. President” for his pro-choice views. Schenk helped Terry found Operation Rescue, one of the most extreme and controversial anti-choice groups in America.

Schenk continues to work closely with other anti-choice zealots, including his brother Paul, who leads that National Pro-Life Action Center. In the 1990s, Schenck and his brother spearheaded a harassment campaign against an abortion provider in upstate New York who was later murdered by an anti-choice activist who is alleged to have had ties with the Schenck brothers.

Along with his militant anti-choice activism, Schenck has repeatedly questioned President Obama’s Christian faith and in 2006 described a deadly mining disaster in West Virginia as a punishment from God. Schenck is also a staunch opponent of gay rights. He called the repeal of Don’t Ask Don’t Tell an “attack on personal, moral, social and religious sensibilities” and criticized “militant homosexual activists” for holding an LGBT pride parade in Jerusalem, calling it an “abomination.”

Judging from Perry’s other prayer rally organizers, Schenck will fit right in.
