Don't even engage with him. No invitations or offers to make peace. tRump made his bed, and now he has to lie in it. This is going to sound snotty, but truly, nobody who matters will go flocking towards that buffoon.
I've always had deep respect for Congressman Lewis, and I see now why he's been such a formidable force in Congress. He doesn't even have to raise his voice. He has quiet and steely power and knows how to use it.
