I can imagine that perfectly: When Trump was asked about global warming he mentioned "these e-mails." "These" e-mails are the internal communication of the climate researches working at the UK University.
https://en.wikipedia.org/wiki/Climatic_Research_Unit_email_c...
Now, the e-mails didn't contain anything problematic, but were still used against climate researches by the "deniers" who mischaracterised and took the phrases out of the context. Details are in the Wikipedia article above.
Now this NASA guy was "enrolled in Global Entry" meaning the border searchers already knew he works for NASA.
NASA does climate science.
And there's real chance that the searchers have copied the whole content of his phone.
And it's imaginable that again something somewhere can be used as a big media campaign based on something taken out of the context, because it already happened once.
With Trump really mentioning "these e-mails" I can imagine him using such a campaign as a pretext for even more unprecedented measures against climate scientists.
I can't say if this specific case is part of something like that, only that I can imagine something like that.
