how tall is senator mullin

Senator Markwayne Mullin is approximately 5 feet 8 inches tall (about 173 cm).

Since people online sometimes speculate that he is much taller (you may see random claims like 6'4" or 6'5"), those appear in low‑credibility blog-style posts, but biographical writeups that discuss both his MMA background and political career consistently list his height as about 5'8".
