For the record, Trump says it's fake news. Whoever told the New York Times it happened is hiding behind anonymity, because of course they are.
Also for the record, Mueller deserves to be fired. His charge was to find out if the Trump campaign colluded with the Russians. He has found out no such thing, and now he's doing what special counsels always do, which is to ensnare people in process crimes in lieu of any underlying crime so he can justify that any of this ever happened. Mueller is not serving the country in any sort of positive way. He's taking up time and resources in the quest for a pretext to call people criminals, when none of them would have done anything wrong in the first place if Mueller hadn't been appointed to search in vain for a crime that never happened.
