Does Trump knows how to speak Spanish?

lol . He barely can speak ENGLISH! ¯\_(ツ)_/¯

I suspect not, but it doesn't really matter.

His native English is often literally nonsensical.  He jumps around from topic to topic.  He doesn't always use complete sentences even when it's absolutely necessary for comprehension.  He often speaks for a long time without saying anything of consequence.

His Spanish would certainly not be better than his English, which is awful.  

Whether you support Trump or not, the man is simply poor at public speaking.  

Pienso que no.
