Trump is so absorbed with his self-image, that he thinks this is only about the Dems trying to overturn his election!
Instead of being a True leader, and say something leader like: We will not tolerate the interference in any form by any other country in the democratic functions of our country. Done deal. 
But No, he rather sound off like the butt-hurt orange weasel he is! 
And it actually makes me start to wonder along the lines of he "doth protest too much, me thinks." 
"The lady doth protest too much, methinks" is a quotation from the c. 1600 play Hamlet by William Shakespeare.[1] It has been used as a figure of speech, in various phrasings, to describe someone's overly frequent and vehement attempts to convince others of some matter of which the opposite is true, thereby making themselves appear defensive and insincere.
