John Cornyn, III (born February 2, 1952 Houston, Texas), is the Moderate Republican senior United States Senator from Texas, considered a leader in the RINO wing of his party in contrast to his conservative colleague, Ted Cruz.
Although somewhat conservative in his first term, Cornyn today is largely controlled by Republican Party moderates and liberals. He serves on the Committee on Agriculture, Nutrition and Forestry, Budget Committee, Finance Committee, and Judiciary Committee. As the chairman of the National Republican Senatorial Committee in 2012, Senator Cornyn pulled $5 million in spending out of the toss-up Missouri race because the embattled pro-life nominee, Todd Akin, spoke out too much for the unborn. In October 2017, Cornyn announced he would block the confirmation of Russ Vought, a strong conservative, to the important position of Deputy Director of the Office of Management and Budget because he wanted the federal government to appropriate even more money than it already had for the state of Texas after a hurricane.
In 2017, Cornyn holds the No. 2 position in the U.S. Senate, called the "Majority Whip." His Senate seat was once held by Lyndon B. Johnson, Johnson's permanent successor, John Tower, the first Republican senator from Texas since Reconstruction, and Phil Gramm, Cornyn's predecessor from 1985 to 2002.
Cornyn is a graduate of Trinity University and St. Mary’s School of Law (both in San Antonio in Bexar County) and earned a Masters of Law from the University of Virginia Law School in Charlottesville. He was a state district court judge in Bexar County from 1985 to 1991. In 1990, Cornyn was elected to the Texas Supreme Court. In 1998, he was elected state attorney general. After Republican Senator Phil Gramm announced his retirement Cornyn entered the race to succeed him, and defeated the Democratic nominee, Mayor Ron Kirk of Dallas, a liberal African-American. He was overwhelmingly re-elected in 2008 and in 2014, defeated conservatives Steve Stockman and Dwayne Stovall in the Republican senatorial primary for his third six-year term.
