You'll note there's nothing to not believe. The journalist was simply pointing out that there is no apparent reason for this announcement to come from Intel's CEO while he's in the Oval Office. Nothing in the announcement, brief, or subsequent details suggests this has anything at all to do with Trump. Except the location of the announcement.
H's just confused about why it took place in the Oval Office. There's two possible reasons really:
(1) Trump did something to prompt this decision. In which case, I would expect, based on Trump's personality, that he'd be telling everyone who will listen how he did it.
(2) Trump didn't do anything except arrange for the announcement to come from inside the Oval. I personally think this is the case - it gives people (like you) that want to believe he's doing something a talking point, valid or not - and two, it gives Intel the perception of being both pro-trump and meh-trump at the same time.
The short version here is that we're being fed something. I hesitate to call it bullshit, because nobody said anything weird - but it certainly looks like people are trying to play some kind of game here.
