CNN legal analyst Elie Honig said President Trump's tweet attacking former US Ambassador to Ukraine Marie Yovanovitch as she testified today was "textbook" witness intimidation.
Honig, a former federal and state prosecutor, said Trump "tweeted out a direct personal attack on this witness clearly related to her testimony while she was testifying."
"I've prosecuted witness tampering cases. I've tried witness tampering cases. To me this is right down the middle. The question who is going to prosecute it?" Honig said.
He went on to say there are questions whether a sitting president can be prosecuted, adding "the question is what is Adam Schiff going to do."
