Rick Santorum: 'Maybe He Is Eating Mushrooms' [UPDATED]

This post has been updated.

During a stop in Iowa on Monday, Republican presidential candidate Rick Santorum took aim at Attorney General Eric Holder for his support of trying terror suspects in the civilian court system as opposed to in military tribunals.

[Note: This post initially indicated that Santorum's remarks were made in reference to the president; however, the Republican hopeful clarified during an appearance on Fox News that he was speaking about Holder, not Obama.]

"Maybe he is eating mushrooms," said Santorum in speaking out on the issue. "I don’t know what he is doing. You can’t even make this up."

The former U.S. Senator from Pennsylvania added, "It is giving terrorists your constitutional rights. ... This is truly frightening that we have leaders in this country that believe that."

Last week, Holder defended the Obama administration's position on the issue in a speech at the American Constitution Society Convention.

In other Santorum campaign news, the presidential hopeful is out with a new web ad targeting newly-minted Republican rival former Utah governor Jon Huntsman, as well as former Massachusetts governor Mitt Romney on the issue of abortion.

Santorum wrote in an email to supporters on Monday:

Gov. Mitt Romney refused to sign the pledge, and then tried to talk his way out of it. I won't go into the reasons why because frankly there are none.

It's really quite simple. Either you support the unborn and are willing to take five minutes to sign a pledge saying you do, or you don't. Clearly Gov. Romney does not and should be held accountable for his position. I was willing to give him the benefit of the doubt that he was once pro-choice, but has seen the error of his ways and was now pro—life. However, not signing this pledge has stunned me to learn that once again Governor Romney is NOT pro-life and cannot claim to be to win a Republican primary.

The new spot out rolled out by Santorum criticizes Huntsman -- who formally launched his presidential campaign on Tuesday -- for not adding his name to the pro-life pledge while linking him to Romney on the issue.
