They were invited by Sen Graham, after he consulted with Cindy McCain. I have no idea why they decided to come as must have been quite humiliating to listen to all the Trump bashing. Meghan looks like she is using food to deal with her anger issues. Get some professional help Meghan.
Their only mistake was to expect the proceedings to be Civil in Honoring McCain.
It isn’t their fault that the Speakers showed themselves to be classless lowlifes.
