According to former New York City homicide prosecutor Paul Callan, there is no way Donald Trump could not have known that his 2016 presidential campaign was working with the Russians to get him elected.

Speaking with CNN host Jim Sciutto, Callan -- a CNN legal analyst -- was asked about Trump legal adviser Rudy Giuliani confirming there may have been collusion between the Trump campaign and Russians.

Callan began by noting the money that was reportedly paid to the president's alleged mistress Stormy Daniels at Trump's behest was small potatoes for special counsel Robert Mueller's investigators before turning to campaign chairman Paul Manafort serving up polling data to the Russians.

"The question becomes, does Mueller have evidence that ties anyone who may have colluded on the Trump team back to the president?" host Sciutto asked. "How hard of a line is it to draw and how significant?"

"Well, it is a difficult thing to do although I think if you step back, most people say, 'how could the president not know his campaign manager is slipping polling information to the Russians?" Callan replied. "How could the president not know when his own son orchestrated a meeting in the Trump Tower with Russian representatives to get dirt on Hillary Clinton? It all looks like the president knew a lot."

"But the defense here is: he didn't know," he continued. "We'll have to see what Mueller has. I'm assuming there may be other things because the Mueller investigation has been thorough and detailed in every case when an indictment is filed."
