Carper is "shocked and concerned" and Coons believes it raises serious questions.

Sen. Tom Carper:

“I am shocked by President Trump’s firing of FBI Director James Comey, and I am deeply concerned about what it means for the ongoing investigation into Russia’s interference in our last presidential election.

President Trump’s decision today raises more questions than it answers. What changed since the president took office for him to lose confidence in Director Comey’s ability to do the job? Why did Attorney General Sessions, who has recused himself from the investigation into Russia’s interference into the presidential election, recommend Director Comey be fired or have any role in that decision?

Now more than ever, it should be clear we must appoint a special counsel to finish the job in order to ensure that any findings about Russia’s influence in the last election are not clouded by partisan controversy. In addition, as we move forward with a new FBI Director, Democrats and Republicans must come together to ensure that he or she is beyond reproach, eminently qualified and totally independent in thought and deed.”

Sen. Chris Coons:

“President Trump’s abrupt firing of FBI Director Comey and his brief public letter raises more questions than it answers.  The reasons the Trump administration cites for this action have long been public: Director Comey made announcements about the investigation into Secretary Clinton's emails that departed from longstanding FBI and DOJ guidance in the summer and fall of 2016. 

While Director Comey has rightly been questioned and criticized for those actions, months have gone by without any action from the Trump administration.  Director Comey has also recently publicly confirmed that the FBI is currently investigating potential collusion between the Trump campaign and Russia.

The President should provide a prompt, full and public explanation of why he decided to take this step, and Director Comey should be recalled to testify before the Senate Judiciary Committee about whether the ongoing investigation has been compromised. 

Russian interference in our democracy is one of the most important threats facing the United States, and this action by President Trump may make it more difficult for us to get to the bottom of how Russia interfered in our election and how we should respond to keep our future elections safe.”
