Hillary Clinton recklessly discussed, in emails hosted on her private server, an Iranian nuclear scientist who was executed by Iran for treason, Sen. Tom Cotton, R-Ark., said Sunday.

"I'm not going to comment on what he may or may not have done for the United States government, but in the emails that were on Hillary Clinton's private server, there were conversations among her senior advisors about this gentleman," he said on "Face the Nation." Cotton was speaking about Shahram Amiri, who gave information to the U.S. about Iran's nuclear program.

The senator said this lapse proves she is not capable of keeping the country safe.It is shocking to hear that the email leaks may have put peoples lives at risk. Also that the NSA and US intelligence hate her so much that they were willing to hack her server and give the information to Wikileaks. Also, the extent of involvement/corruption by Hillary and the Clinton Foundation on many issues is stunning.
