Presidential nominees are given national security briefings during the 4 months prior to the election. We now have indications that Donald Trump has dangerous ties to Putin. He has called on Russia to do espionage against sensitive State Department emails. He has offered to support Russia by dismantling our NATO treaty agreements. His son said in 2008 that they got a lot of money from Russia. He has said many times he admires Putin.
We have never had such a national security danger as we have now. The courtesy of sharing national security briefings with the Republican nominee MUST NOT happen. Our national security is at stake.
