# Mike Crapo **Mike Crapo** (b. 1951) is a Republican U.S. Senator from Idaho (since 1999) and chair of the [[Senate Finance Committee]] (since January 2025) — the Senate's tax-writing chokepoint for the [[Tax Cuts and Jobs Act]] extension and the reconciliation package. As Banking Committee chair in 2018 he authored the partial Dodd-Frank rollback (Economic Growth, Regulatory Relief, and Consumer Protection Act). ## Why he matters for the KB Finance chair = the Senate end of the tax-cut extension machinery; his Dodd-Frank rollback authorship also makes him a named node in the financial-deregulation through-line at [[Dodd-Frank Act]].
