Michael Dean Crapo (/ˈkreɪpoʊ/ KRAY-poh; born May 20, 1951) is an American lawyer and politician serving as the senior United States senator from Idaho, a seat he has held since 1999.

Born in Idaho Falls, Crapo is a graduate of Brigham Young University and Harvard Law School.

His brother Terry Crapo was majority leader in the Idaho House of Representatives from 1968 to 1972 and an influential political figure until his death from leukemia in 1982.

After three terms in the House, he ran for the open seat in the U.S. Senate in 1998 when Dirk Kempthorne vacated it to run for Idaho governor.

Crapo was elected with 70% of the vote, and became the first member of the Church of Jesus Christ of Latter-day Saints to represent Idaho in the Senate.

[7] On February 12, 1999, Crapo was one of 50 senators to vote to convict of impeachable offenses and to remove Bill Clinton from office.

[8] In the 111th Congress, Crapo served on the following Senate committees: Banking, Housing and Urban Development; Budget; Environment and Public Works; Indian Affairs; and Finance.

[12] In 2017, Crapo was one of 22 senators to sign a letter[13] to President Donald Trump urging him to withdraw the United States from the Paris Agreement.

The next Supreme Court justice will make decisions that affect every American and shape our nation's legal landscape for decades.

[15]In September 2020, with less than two months to the next presidential election, Crapo voiced support for an immediate Senate vote on Trump's nominee to fill the Supreme Court vacancy caused by the death of justice Ruth Bader Ginsburg, once a "well-qualified candidate" was put forth.

[16] For his tenure as the chairman of the Senate Banking, Housing, and Urban Affairs Committee during the 116th Congress, Crapo was given an "F" grade from the non-partisan Lugar Center's Congressional Oversight Hearing Index.

[18] He opposed removing Trump from office, saying that the "country is too divided" and that invoking the Twenty-fifth Amendment to the United States Constitution "would only make matters worse".

[19] In October 2023, Crapo visited China as part of a bipartisan congressional delegation led by Senate Majority Leader Chuck Schumer and met with Chinese President Xi Jinping.

The delegation also met Foreign Minister Wang Yi, National People's Congress Standing Committee Chairman Zhao Leji, and Shanghai Communist Party Secretary Chen Jining.

In 1998, he supported a bill that made it illegal for minors to cross state lines to get abortions in order to avoid parental consent laws.

[30][31] The same year, he joined 12 other senators vowing to filibuster any attempts by Democrats to introduce additional gun control regulations in the wake of the Sandy Hook Elementary School shooting.

[33] In January 2017, the NRA praised Crapo for introducing the Hearing Protection Act, which would make access to gun silencers easier.

On January 4, 2013, Crapo pleaded guilty to DUI in connection with a December 2012 incident and received the standard punishment for a first-time offender in Virginia.

[43] He issued a public apology just after his arrest,[44] and various Idaho media outlets criticized him in light of his religion's temperance tenets.
