At his speech in Phoenix last week Trump made a claim so blatantly untrue on its face and so easily disproven, it just makes no sense why he would say something like that. It seems so patronizing to his supporters that they might believe it, and he just reeled it off as an afterthought.

He began the speech with this whopper:

“Now that you’ve heard about Hillary Clinton’s plan, about which she has not answered a single question, let me tell you about my plan.”

Think of it. Does he actually believe that Hillary Clinton has not answered a single question about her immigration plan?

She was repeatedly asked about immigration during March’s Democratic debate with Bernie Sanders. Here’s a taste:

Here is an interview on Vox where Clinton is asked several questions about her immigration policy.

There are plenty more, but are two instances, one more than needed to disprove Trump’s assertion that she hadn’t answered “a single question.” This statement even got a coveted “Pants On Fire!” rating from Politfact.
