Reportedly, many sanctuary cities’ mayors are saying they’re going to defy Trump on this but it is in his Contract with the American Voter:
FIRST, cancel every unconstitutional executive action, memorandum and order issued by President Obama
SECOND, begin the process of selecting a replacement for Justice Scalia from one of the 20 judges on my list, who will uphold and defend the Constitution of the United States
THIRD, cancel all federal funding to Sanctuary Cities
FOURTH, begin removing the more than 2 million criminal illegal immigrants from the country and cancel visas to foreign countries that won’t take them back
FIFTH, suspend immigration from terror-prone regions where vetting cannot safely occur. All vetting of people coming into our country will be considered extreme vetting.
I really do not see him reneging on that one.
We can also expect to see him deporting all illegal immigrants who are arrested, according to a Transition Team member.
It will probably take an act of Congress to stop the money that is flowing to the U.S. Bishops for programs caring for immigrants, but maybe that funding will stay intact for the time being as Trump focuses on the criminals first.
