Sarcasm?

Trump says his comments about Russia hacking our systems to find Hillary Clinton's missing emails was sarcasm http://www.cnn.com/2016/07/28/politics/donald-trump-russia-hacking-sarcastic/.  I think I know sarcasm, and when I list to his remarks, I do not hear sarcasm.

This is Trump, once again, recreating his history.  This is a common theme with Donald Trump.  He says something, then denies saying it, or tries to change its meaning.  And then he says Hillary Clinton is crooked.  How crooked can he get? Look at his businesses. They so misrepresent what they are. 

I just think that sarcasm about encouraging espionage is in poor taste coming from anyone, but coming from someone who is running for President?  It shows his lack of judgement and self-control.  This is not leadership behavior.
