He does not have a Telegram account.
John B. Wells interviewed General McInerney on last night’s Caravan to Midnight and specifically asked if that is his Telegram account. The General said “no”.

Take that "no" with a grain of salt in the same spirit you would the "no" when Q was asked whether JFK Jr. was alive.
I doubt that the Lt. General's Twitter account is "his" any more than DJT's is. They are Q-Team accounts.
