DULUTH, Minn. (AP) — Democratic state senators are pressing for more answers on why the coach of Minnesota Duluth women’s hockey team is being let go.

Shannon Miller has coached UMD to five NCAA national championships but the university isn’t renewing her contract after this season. School officials have cited a $4.5 million budget deficit as a primary reason. Miller’s $215,000 salary makes her the highest-paid coach in women’s hockey.
