nomination of Supreme Court Associate Justice Abe Fortas to be elevated to the position of Chief Justice, charging President (and former Senate Majority Leader) Lyndon B. Johnson with cronyism, noting the close relationship between the two. Fortas resigned his Associate Justice seat in May 1969 when it was discovered Fortas had been paid a $20,000 a year retainer by Louis Wolfson, a close friend and former client, since 1966. Griffin voted in favor of the Civil Rights Act of 1968 and the confirmation of Thurgood Marshall to the U.S. Supreme Court. He became the Republican Whip in the Senate on September 24, 1969, and served until 1977. In 1974, he wrote to President Richard Nixon to inform him that if the White House did not release tapes that the Watergate Committee subpoenaed, the President would face impeachment and trial in the Senate. He also told the President that he considered the failure to comply with the subpoena as an impeachable offense. Up to that point, Griffin had been a supporter of the President. Griffin was an unsuccessful candidate for reelection in 1978, narrowly defeated by former Detroit City Council president Carl Levin. He initially announced in April 1977 that he would not run for re-election in 1978, saying that he was tired and that Washington needed new blood. He went on to miss a third of the votes in 1977. He changed his mind later in the campaign and Levin used his own words and his attendance record against him during the campaign. Later, Griffin served as a justice of the Michigan Supreme Court from 1987 to 1994. His son, Richard Allen Griffin, was a judge on the Michigan Court of Appeals from 1989 to 2005, when he was appointed by President George W. Bush to the United States Court of Appeals for the Sixth Circuit. During the elder Griffin's first Senate campaign in 1966, a suburban Detroit rock band, Doug Brown and the Omens, released a promotional flexidisc in support of Griffin's candidacy. The song, "Give Bob The Ball" (which extolled Griffin's "youth and experience") has been included on the garage rock compilation album Friday At The Hideout. Personal life and death Griffin was a resident of Traverse City, in Northern Michigan. He married Marjorie Anderson of Ludington in 1947. Together, they had four children, including Richard Griffin. Griffin died on April 16, 2015, aged 91. He is buried
