Alexa's shockingly surpressing info.

I know alexa is an in home spy, anyways, wanted to see if it would play Trump's speech from today in Alamo, Tx. The first time I asked the exact same thing, it said "I can not find Donald Trump's speech on immigration" which I thought was weird since I didn't say a word about immigration. When I tried to record it, it changed its response. Weird.
