President Trump on Tuesday said he was unsure whether Saudi Crown Prince Mohammed bin Salman knew about the murder of writer Jamal Khashoggi.

"King Salman and Crown Prince Mohammad bin Salman vigorously deny any knowledge of the planning or execution of the murder of Mr. Khashoggi. Our intelligence agencies continue to assess all information, but it could very well be that the Crown Prince had knowledge of this tragic event - maybe he did and maybe he didn't!" Trump said in a lengthy statement.

AB Stoddard, associate editor and columnist at RealClearPolitics, joins Fox News Radio's Guy Benson to discuss President Trump's response to Saudi Arabia. 

On Trump's response to Saudi Arabia: What's so concerning to me about President Trump, and has been since 2015, is the question of whether or not he's truly fit to be Commander In Chief and best represent us President of the United States. We are the hope of the world. His response today did not just treat our values and our moral compass and our position of strength and hope and leadership in the world that our democracy is based on he didn't just treat that has a trivial inconvenience, he was almost contemptuous of it... This is not a person who is understanding or commitment to the demands of the office of the presidency of the United States. (3:01)

On Trump not denouncing the murder: It's an invitation to our allies and our adversaries that he will put up with more of this.  When have you heard him actually articulate our commitment to these values? When he defines America First I can't remember hearing him champion these values, what sets us apart.  (8:16)

On Trump going off on domestic critics and not on foreign adversaries: My big concern always is that he believes that he's running a quasi kingdom and that there is no Congress,  courts, or Constitution. That's my worry. It's been there since 2016 because of the things the President says and because of the things that the President does. He went after the 9th circuit today and said it's an Obama judge. Everything is politicized, whether it's Admiral McRaven, a Navy Seal, the judiciary. It doesn't matter. It's always about political enemies and who's on my side. It's not about a separate and coequal branch of government and a system of checks and balances.  (9:10)
