The date in this sentence is off by three days. The U.S. Senate's official Teapot Dome history states that John B. Kendrick introduced the resolution on April 15, 1922. Another Senate historical page says, "On April 15, Kendrick introduced a resolution in the Senate" and identifies that measure as the one that set the Teapot Dome inquiry in motion. Those official Senate sources contradict the article's claim that Kendrick introduced the resolution on April 12.

This sentence misidentifies Harry M. Daugherty's office. Daugherty was the 51st Attorney General of the United States, not the president. The Department of Justice's official historical biography states that he "was appointed Attorney General of the United States on March 4, 1921, serving under Presidents Warren G. Harding and Calvin Coolidge until resigning on March 28, 1924." That directly contradicts the article's statement that he "served as president."

This sentence assigns leadership of the Teapot Dome investigation to the wrong senator. The Senate Historical Office says Robert La Follette arranged for the Committee on Public Lands to investigate the matter, but that the committee's leadership allowed Thomas J. Walsh to chair the panel. Another official Senate history explicitly describes Teapot Dome as the Senate investigation "led by Thomas J. Walsh of Montana." So La Follette was important in getting the inquiry started, but he did not lead the committee investigation in the way this sentence claims.

This sentence overstates the length of Teapot Dome's inactivity. The Department of Energy says that after the Supreme Court invalidated the leases in 1927, the reserve was shut down, but "apart from some exploratory and offset wells drilled in the 1950s and 1960s, the oilfield was essentially closed until full development resumed in 1976." A DOE environmental assessment is even more explicit: production was discontinued after 1927 and renewed between 1959 and 1976 in a limited program to prevent drainage to adjacent private wells. Because there was drilling and limited renewed production before 1976, the claim that the field was simply idle for 49 years is inaccurate.

This sentence is inaccurate in two ways. The tax-return law is not a general congressional subpoena power: 26 U.S.C. § 6103(f) gives access upon written request from the chair of the House Ways and Means Committee, the chair of the Senate Finance Committee, or the chair of the Joint Committee on Taxation. An official House filing preserved by GovInfo explains that the 1924 precursor likewise allowed the congressional tax committees to call on the Secretary of the Treasury for return information. Separately, the Senate explains that Congress's power to issue subpoenas and compel testimony was established in McGrain v. Daugherty (1927).
