Maybe the simplest way to evict him, is to arrest him just after Biden is sworn in. Trump would no longer be President, so he could be indicted for those 10 Obstruction of Justice counts as Mueller said in testimony to Congress. (That's rather important: Mueller said it was up to Congress if they wanted to impeach him, but he also said his indictment would have to wait until he was out of office. NOT "never".)
The Secret Service could continue to protect him as an ex-President, as the FBI arrested him, and took him into custody. They would just have to do it in federal courtrooms and detention facilities.
Or maybe he manages to get pardoned, so DC cops have to arrest him to face charges in New York. Secret Service can go along in the extradition van.
