I agree. The allegations against him may be true or false. Perhaps he may have something to say about them. If so, I hope it is better than what presidential candidate Hillary Clinton said when confronted about her claims to have come under sniper fire in Bosnia, when she said little more than that she "misspoke."
In any event, his veracity should be weighed against what he disclosed about the spying on us, not something else.
This seems to be a classic case of "Play the man, not the ball." That's OK for sporting contests, but this is rather different.
He’s being smeared by people who know they were spied on. And not one person who smears him denies the government is doing what he said it is doing.
