Asking about her husband’s public comments about President Trump and President Trump’s public comments about her husband is fine. That is journalism (such as it is today). Asking about the state of their marriage is off-limits and she should be offended. Wallace never should have asked the final question.
Nobody is learning bere. What POTUS does is important. What POTUS says is about control of the media. Distraction is a device. He’s using that device. The husband is a tool. Criticise POTUS for what is done and not done. Don’t be taken in.
