Of course he had the affairs with Daniels and McDougal, then continually lies about it. He lied about sillier stuff, like not posing as his own publicist, John Barron. They're really stupid lies, since nobody seems to care about them.
The more troubling aspect is the fact he's got people like Cohen and Pecker out there cleaning up for him with payoffs during an election. It would mean we have a president who is potentially compromised and subject to being leveraged by it. That's a real problem.
