Like I stated earlier, he was previously asked by Trump and Sessions to stay. He was the main "swamp drainer" and he was respected by Republicans and Democrats. He was starting to investigate many of Trump's businesses in New York. So, no, not wrong Kaos, trying doing research before posting.
Regardless of what he said about Trump/Sessions saying he would stay on, I've not read anything in an official capacity on what Trump actually told him. Maybe Trump wanted him to stay on a month or two, and he thought that meant permanently. Maybe Trump said stay on for a month, and let me think about it. I don't know, and I imagine, no one you read really knows either. So many other legitimate things to worry about, I just feel this is really nothing.
Anyway, I'm glad he is well respected by both Republicans and Democrats. You know who else is? Neil Gorsuch.
