This shit is a year old but for those not up to speed it explains what Comey is and why DJT fired him when he was 3,000 miles away:

Begin by noticing how the President fired Comey when Comey was 3,000 miles away from his office, that Comey had no inkling he was being cut, that all his files, computers, and everything in his office were seized by his boss Sessions and the Justice Department. This was not a violation of protocol, it was tactical. Notice how Prez Trump compartmentalized the strike and did not inform any of his White House “staff” to prevent leaks. Notice how he emasculated Comey and the swamp denizens by letting them know in a tweet that the Attorney General got information (surveillance “tapes” from the seizure of Comey’s office) to let Comey and his handlers know that Trump’s DOJ has the goods on them. This was a brilliant, strategic and totally imperative move at exactly the right time against horrible, evil and corrupt powers infesting our government.
