Q: (CNN) President Donald Trump is under fire again, this time for his firing of former FBI Director James Comey. But many of his supporters aren't joining the outcry. CNN spoke to Trump backers across the country, and while some of them expressed surprise at Comey's ouster, few said it changed their image of the leader of the free world. Here's what they had to say: Jake Lee, business owner Lee, 46, of West Hollywood, California, said he believes Trump made "the right decision" in axing Comey. "As far as the Comey thing goes, I think he gave him plenty of chances. I think what became the last straw was when he (Comey) made that statement about the classified emails showing up on (Hillary Clinton aide Huma Abedin's and her husband, former Congressman Anthony Weiner's) laptop. You can't have rules for the elitist ruling class and not have those rules apply to everybody else. I think in my opinion that was part of (Trump's) decision. The guy likes to run a tight ship."Many Trump voters across the country say James Comey's firing doesn't change their opinion of the President"I was hoping Trump would've done a lot better with his presidency so far," Kentucky business owner says 
 Question:And that's part of why I voted for (_), because he wasn't a politician.

A:
Donald Trump
