Yes, she is and it is not as dumb as it sounds. She is saying that the temporary workers who came here seasonally to pick crops would go back home to their families after the picking season was over. When they put up walls at the entrance points in San Diego and El Paso those workers became afraid to go home for fear they couldn't come back the next season so they stayed and brought their families to the US instead. Now they are permanent, though illegal, residents. So trying to stop the problem only increased it.
Now, however, it is too late to correct that problem that was created by closing the borders, partially, so we must close it completely. That was an example of unintended consequences.
I find it difficult to believe that is the case, since it is clear that many MANY people cross the border, going both directions, regardless of the meager attempts we've made at *securing* it.
I find it hard to believe anyone even BELIEVES that.
