The above is a flat out lie.
I only question what I heard as a documented tenet of the Libertarian party....
3.4 Free Trade and Migration:
We support the removal of governmental impediments to free trade. Political freedom and escape from tyranny demand that individuals not be unreasonably constrained by government in the crossing of political boundaries. Economic freedom demands the unrestricted movement of human as well as financial capital across national borders. However, we support control over the entry into our country of foreign nationals who pose a credible threat to security, health or property.
