He's making things up now:

SANTORUM: I was just reading something last night from the state of California. And that the California universities – I think it’s seven or eight of the California system of universities don’t even teach an American history course. It’s not even available to be taught.

Here's the video (it's low quality):

And he's right in one small way — the University of California school in San Francisco doesn't offer a course in history.  In fact, it doesn't offer any course in the humanities.  Because it is a medical school.

On the other hand, the other nine schools of the UC university system – Berkeley, Irvine, Davis, Los Angeles, Merced, Riverside, San Diego, Santa Barbara, and Santa Cruz all offer numerous American history courses. Some even require students to take U.S. history before they can graduate.

It got me to wondering what Santorum actually read.  He said he "just read" this fact.  Well, it didn't take me long to figure it out.  He most likely read an op-ed in the Wall Street Journal by Peter Berkowitz entitled "How California Schools Indoctrinate Students".  It's a ridiculous piece, but even then, Berkowitz merely wrote:

"None of the nine general campuses in the UC system requires students to study the history and institutions of the United States."

(emphasis mine) which of course is a far cry from claiming that such courses aren't offered.

So it looks like Santorum needs to go back to school himself — to bone up on his reading comprehension skills.

(And by the way, here's a scathing retort to the silly WSJ piece by Berkowitz).

UPDATE:  Here's a screenshot of the University of California website.  Yes, both Santorum AND Berkowitz were just making shit up:

From the site:

All undergraduate degree programs at UC require study in American history and institutions. This requirement may be met through examination or enrollment in specific courses. Each campus decides how its students may meet the requirement.

Satisfactory completion in high school of a one-year course in U.S. history or a half-year course in U.S. history and a half-year course in American government, fulfills this requirement at all UC campuses except UC Santa Barbara. (At UCLA, students must also have earned a B average in these courses.) UC Santa Barbara requires students to complete a college-level course. 

Satisfaction of a community college's history and institutions requirement will also meet the requirement at most campuses. It is highly recommended that students complete this requirement before they transfer.
