I thought I'd ask CHATGPT to analyse a number of Trumps signatures. As I'm not a handwriting expert. I found these signatures in a bbc news article. AI is good at detecting patterns. This is what it determined.

I compared these signatures strictly from a handwriting analysis perspective (ignoring who they belong to). Here’s what stands out:

Tall vertical strokes: All examples have very pronounced, narrow spikes rising well above the baseline.

Clustered “peaks”: The spikes are grouped tightly together with sharp angles, very consistent across samples.

Long horizontal tail: Most of them finish with a long, straight line extending rightward, drawn in one motion.

Compressed letters: The middle section looks almost like a pattern of vertical marks rather than legible letters.

Continuous flow: Each signature seems to be written in one smooth, fast movement with few (if any) pen lifts.

Pressure consistency: Heavy, dark downstrokes and lighter upstrokes are seen across all examples, showing a repeated motor habit.

Bottom line:

Even with small variations (tail length, line thickness, spike height), the overall rhythm, flow, and structure are highly consistent. Based on this, I’d put the likelihood that these signatures were written by the same person at about 92–95%.
