I expect everyone here 'supports vetting'. That is obvious and prudent. It was also already in place, in a legal and effective fashion, through the efforts of President Barack Hussein Obama. In his racist zeal and politically motivated angst, President Donald John Trump chose to tear a page from the Rush Limbaugh playbook by claiming President Obama's measures 'Don't Go Far Enough' and had an Executive Order drafted for his own signature that instead went too damned far.
If you had actually paid attention in Third Grade History class, or even Ninth Grade Civics class, you would know the Constitution of the United States of America -- the self-same document that every President, Governor, Mayor, Senator, Congressperson, and civil servant in the nation swears to uphold -- set up three branches of GOVERNMENT. No single branch may rule without input and review by the other two. Our most recent President before this one was fully aware of such points, as he served as a Professor of Constitutional Law for over a decade. That is why his carefully crafted Executive Order remains in place, unchallenged and in full effect, despite the illegal actions of his successor in that Office.
