Don’t ever give Donald Trump the opportunity to catch you in a lie, otherwise “Liar” becomes part of you name, just ask Ted Cruz or Hillary Clinton. And it is now the “lying” fakestream media, as well.
Now it is “Lying” Senator Richard Blumenthal.
Donald Trump sees no reason why he should practice comity with certain Senators and past Senators. And he has not, with some few of them.
Except that Trump did not catch Ted Cruz in a “lie”. Arguably, a mistake. His treatment of Cruz was a needless blot on his otherwise good record.
