Chicago Boyz have a theory - someone sabotaged Melania Trump's speech.
There is also a passage in Melania Trump’s speech which is a direct quote from a Rick Astley song
In other words, Melania Trump’s speech was Rickrolled.
To those who do not recall the fad from 2008 or so, Rickrolling was providing a link which purported to be something else, but in fact linked to a Rick Astley video, in fact, the very video whose lyrics were included in Melania Trump’s speech.
The only plausible explanation for the presence of these lyrics is that someone who participated in the drafting of Melania Trump’s speech intentionally included the Rick Astley lyric, apparently as a signal the speech had been “hacked.”
