Libertarian presidential nominee and former New Mexico Gov. Gary Johnson has come out against proposals to deny Americans on the no-fly list from purchasing guns on the grounds of due process.

“Gov. Johnson believes Second Amendment rights are too fundamental to be denied without due process, and being put on a list arbitrarily by the government is certainly not due process,” Johnson campaign communications director Joe Hunter told The Daily Caller in a statement Wednesday.

[dcquiz] His campaign pointed TheDC to a recent blog post by the ACLU titled, “Until the No Fly List is Fixed, It Shouldn’t Be Used To Restrict People’s Freedoms.” The ACLU is currently in a legal challenge against the no fly list. They say it is “unconstitutionally vague, and innocent people are blacklisted without a fair process to correct government error.”

President Obama and Hillary Clinton have come out in favor of barring people from the no fly list and terror watch list from purchasing weapons. Donald Trump said Wednesday that he is going to meet with the NRA to discuss these proposals.
