Mike Huckabee made some more factual slips Friday with respect to his foreign policy and immigration know-how, saying in Iowa that the United States has more illegal immigrants coming from Pakistan than any other country besides those south of the U.S. border, even though government statistics prove otherwise.

Huckabee warned an Iowa crowd that 660 Pakistanis have come into the country illegally in the past year because of insecure borders. It was a new angle among the candidates reacting on the trail to the assassination Thursday of former Pakistani Prime Minister Benazir Bhutto.

He also said: "We have more Pakistani illegals coming across our border than all of the other nationalities except those immediately south of the border. ... In light of what's happening in Pakistan it ought to give us pause."

But his Pakistan statements don't jibe with the data. Pressed by reporters where he got his figure, Huckabee initially said: "Those are numbers that I got today from a briefing and I believe they are CIA and or immigration numbers."

Later, in a conference call with reporters, he identified the figure as coming from the Department of Homeland Security and news articles, including a March 2006 piece in The Denver Post.

Only that article said 660 Pakistanis entered the United States illegally between fiscal 2002 and 2005 -- not just in one year. And Homeland Security figures for 2006 show that many more illegal immigrants came from India, Korea, China, the Philippines and Vietnam than Pakistan, which didn't even make the chart.

Meanwhile, Huckabee on MSNBC talked about Pakistan's "eastern borders near Afghanistan," even though that border is on Pakistan's western end.

And he suffered another gaffe Thursday when he said it's too early to say whether martial law should "continue" in Pakistan, even though martial law was lifted two weeks ago.

Huckabee's campaign later offered a statement saying "martial law in Pakistan, as a practical matter, should not be viewed as having been completely lifted until the restrictions imposed during that period on the press and judges are removed."

Such comments could play into the hands of critics who say Huckabee's light on foreign policy experience. Since recently admitting to reporters that he hadn't heard about a major report on Iran's nuclear capabilities, Huckabee has sought to fight that accusation.

He's said he's visited dozens of countries and consulted with many national security experts. And his campaign again directed attention to an article he authored in Foreign Affairs, even though he took heat for a line calling the Bush's administration's foreign policy "arrogant bunker mentality." The campaign highlighted a different section where Huckabee says the United States has been too protective of Pakistani President Pervez Musharraf, in turn allowing terrorist groups to grow.

The former Arkansas governor has also been tagged as soft on illegal immigration by his rivals for supporting tuition breaks for children of undocumented residents in his home state, and he has tried to toughen his rhetoric to that end. He released a nine-point immigration plan in early December calling for a border fence and no amnesty.

To that backdrop, he brought up illegal Pakistani immigrants Friday.

"I'm just saying maybe a lot of Americans who live in Pella, Iowa, maybe look halfway around the world and say, 'How does that affect me?'" Huckabee said of the Bhutto killing. "We need to realize that violence and terror is significant when it happens in Pakistan. It is more significant if it could happen in our own cities. And it happens if people can slip across our border and we have no control over it."

Asked if that was "ethnic baiting," Huckabee said "not at all."
