Clinton lied when he said, "I did not have sexual relations with that woman."
The multiple counts of perjury were bad enough, but don't forget the multiple counts of obstruction and conspiracy to obstruct.
He got caught, got impeached, was found Not Guilty.
If you think that committing multiple counts of obstruction and conspiracy to obstruct are worth a not guilty verdict for Bill Clinton, then don't complain when the Republicans hand Trump a not guilty verdict over a trivial offense that he didn't even commit.
Trump told the truth when he said, "I investigated my political rival because he's better than me." And will get impeached and found GUILTY because, no kidding, that's the truth.
The Republicans are not going to find him guilty when he did nothing wrong.
After Bill Clinton, they wouldn't even find him guilty if he actually had done something wrong. But as it happens, he hasn't done anything wrong.
