Rep. Maxine Waters (D-CA) tells MSNBC's Chris Hayes there must be a reason the president and his allies are working so hard to undermine Robert Mueller's probe. Waters speaks about the hypothetical Democratic response if Trump fires Robert Mueller as special counsel.



"We are preparing for what we have to do," Waters said, promising she would come back to Washington if Mueller was fired.



"We are concerned about this buildup that we see," Waters said about the potential of Trump firing Mueller. "We have been watching what they are doing on FOX News, how each day they are adding to the conversation about whether or not [Mueller] is being fair to Trump and whether or not someone who has served on staff has made comments about Trump that are unreasonable. So we can see the buildup and obviously there is a strategy to undermine and discredit the special counsel. We are on alert and we are prepared for any firing or any actions that would remove him from this investigation and we plan to deal with it."











"What is it this president has to hide? Why is it they are so determined to stop [Mueller]? Why are they trying so hard to discredit him?" she asked.



"What is he afraid of?" Waters asked. "If he has not been involved in collusion. If he has not been involved in obstruction of justice. If he has not been involved in money laundering. If he doesn't have a plot lifting the sanctions, working with the Kremlin and the oligarchs of Russia. What is he afraid of and why is going to such lengths to discredit the special counsel?"
