When it comes to judging someone's credibility I look for direct statements.
It is X it is not Y and here's the reason.
Often as we rise to positions of power our language becomes more indirect.
You can't say this - you shouldn't word it so - the press or our partners will take it the wrong way.
My mother used to say, I can stand anything but a liar and I can tell you this is true.
As soon as she hears those lying words her nostrils flare with rage. They do.
You may think you are being tactful but the impression is sometimes the opposite.
Say what you mean and mean what you say, and for goodness sake please keep it simple.
