It is literally not straight from the source.

Source:

"initiating an independent investigation in light of recent reporting that founder and CEO Jensen Huang has been the target of a foreign intelligence effort."

They are investigating a situation where their CEO was the target of an Op - that's totally reasonable and doesn't remotely hint that he has done something wrong.

This is the right thing for the board to do: "We are investigating the situation because we have been informed that foreign actors may have targeted our staff".
