Members of the Deep State have different agendas but they are all united in their hatred of Trump. Hillary hates Trump for an obvious reason. But why Mueller hates Trump came to light only in the last few days. Apparently he wanted his old job at the FBI and Trump told him to f off. Being a GOP-e/Bushie he probably hated Trump anyway but being told to f off added insult to injury.
Mueller is an agent of the globalist class (includes Bushes). Trump is a YUGE thorn in their path of milking American workers.
You are witnessing an epic war between the Donor class (globalists) versus the Voter class (Trump represents them).
