Yes he could and could probably avoid impeachment but would do so at the expense of his entire agenda.
A better way would to recognize he is playing on a far different field than he has ever been on before and his opposition knows the rules of the game far better than he does.
He lost this case because he was not adequately prepared and did not have competent legal representation. He had the constitution, statutes, and common sense on his side, but the other side had the press, good lawyers, and a sympathetic court on their side.
His first act should be to hire a top flight lawyer from a major Washington law firm who has extensive contacts and experience in government. Next thing would be to listen to him or her and stop pretending that he knows everything. He can't bully, intimidate, embarrass, or trick these people into falling in line. He will have to beat them at their own game and, like it or not, good lawyers are the special forces in this conflict. It is time for amateur hour to end. Twitter might excite his base and even relieve his frustration, but it will not help him win in any court.
Oh ye of little faith, yes we sent him up there to CHANGE those rules (the ones that the Washington lawyers & politicians play by in lieu of the Rule of Law established by We the People and enshrined in the Constitution of the U.S.). MAGA!! Drain the swamp!!
