Very odd that at a time like this he’s on an unannounced trip to Rome, and no one is quite sure on why he’s there or who he is meeting with. Apperantly, a Russian national named in the Mueller report is in Rome as well. Not saying that they’re meeting, but given Trump’s willingness to drop Barr’s name during the phone call with the Ukrainian president, it’s not a good look. Just overall a very odd coincidence.
Doubt it’s anything of note. If there were a reason to cancel and come home early, I think an impeachment investigation with his name all over it might be a good one, however.
