A couple of weeks ago, we reported extensively on a conference in Iowa organized by extremist pastor Kevin Swanson, at which three Republican presidential candidates joined Swanson on stage shortly before he went off on a series of rants about how the biblical punishment for homosexuality is death, Harry Potter is bringing God’s judgment on America, and how if your gay child gets married you should show up to the wedding covered in cow manure.

MSNBC’s Rachel Maddow ran a segment on the conference, but other than that, as a number of commentators have noted, the media has been strangely silent on the Republican candidates’ participation in this event.

Today, Des Moines Register columnist Rekha Basu reports that she reached out to the campaigns of the three candidates, Ted Cruz, Mike Huckabee and Bobby Jindal (who has since dropped out of the presidential race), and found them rather reluctant to talk about it.

A spokesperson for Huckabee, who at the event deflected a question about Swanson’s extremism, told Basu after viewing video of some of Swanson’s remarks that Huckabee “appreciated the opportunity” to speak at the conference. The Cruz and Jindal campaigns didn’t bother to reply at all. (Before the conference, Cruz had been asked about his participation by CNN’s Jake Tapper, but brushed off the question.)

Calls and emails seeking a reaction to Swanson’s remarks by spokespeople for Cruz and Jindal (who suspended his campaign Tuesday) went unanswered. Huckabee’s spokeswoman Alice Stewart asked for documentation and was sent a video link. She responded the next day saying, “Gov. Huckabee appreciated the opportunity to speak with an audience in Iowa about the importance of standing up for our religious liberties.”

Basu also reached out to The Family Leader, an influential Iowa conservative group that sponsored Swanson’s conference and will be hosting candidates for a “presidential family forum” later this week. A Family Leader spokesman at least went as far to say that the group doesn’t condone executing gay people, but didn’t comment on the wisdom of sponsoring Swanson’s conference:

Asked if Vander Plaats or the Family Leader condemn Swanson’s remarks, Drew Zahn, its director of communications wrote in an email: “The Family Leader absolutely condemns any call for violence against homosexuals. Our involvement with the conference was intended to advocate and preserve our First Amendment religious liberties and the rights of conscience for all Americans. The Family Leader consistently advocated the Bible’s principle of treating others as you would be treated, a principle come to life in the friendship between TFL President Bob Vander Plaats and One Iowa’s Donna Red Wing.” But Zahn wouldn’t say whether the organization would express those views to Swanson, or would have withdrawn sponsorship from the program if they had known what he would say.

We really wonder how long Cruz and Huckabee will be able to continue to plead ignorance about Swanson’s extremism after being asked about it repeatedly.
