I don't believe that there is anything wrong with this term. Some immigrants are legal others are not. A nation has every right to determine which people it allows into its country. I am not even sure whether Hillary believes in her apology (it wouldn't surprise me as she is documented liar and possibly a sociopath) but clearly her remarks here are designed to appeal to the party's powerful left wing base. The U.S. can do so much better than electing Hillary as its next president. If she does become POTUS it will be a great shame for that her scandal ridden legacy should be associated with the first female President of the US.
