Bachmann Signs Illegal Immigration Pledge, Cain Makes Border Fence Joke

Republican presidential hopefuls Michele Bachmann and Herman Cain had some strong words about illegal immigration this weekend when they campaigned in Iowa and Tennessee, respectively.

Bachmann said that finishing a fence between the U.S. and Mexico would be her first priority, The Associated Press reported. She also signed the Americans for Securing the Border pledge, ABC News reported.

And it will be every mile, it will be every yard, it will be every foot, it will be every inch of that border, because that portion you fail to secure is the highway into the United States, she said, The Los Angeles Times reported.

Cain made a comment about a fence between the U.S. and Mexico being electrified so that it could kill any illegals who tried to go through it, The New York Times reported.

Cain later went on NBC's Meet the Press and told David Gregory that he was joking when he made the comment.

That's a joke, Cain said. I've also said America needs to get a sense of humor.

Cain said the same thing during a Fox Republican debate in August when asked about comments he had made about an electrical fence.
