A look at why some Trump voters now feel let down, framed as a sign of growing anger inside his base.

• Some longtime Trump supporters feel betrayed, believing he has joined forces with the same establishment that once went after him.
• They trusted him because his first term started no new wars and because he was hounded by prosecutors and threatened with prison.
• That persecution was seen as proof he would never team up with the establishment against his own voters.
• January 6 is described here as an FBI setup, with claims that FBI informants were inside the Capitol before the riot.
• The frustration is that questions about FBI involvement still go unanswered.

Outlook: Expect more open friction between Trump and parts of his base as distrust of him and the FBI keeps building.
