Johnson was an
alcoholic. In his later years, his drinking, coupled with physical disability caused by a broken hip, limited his effectiveness as a member of his brother's organization. In 1970 Johnson wrote a memoir,
My Brother Lyndon, which praised his brother in most respects, but was critical in others. At the time, Johnson indicated that he was estranged from his brother, but said his book was not the cause. The two reconciled before Lyndon Johnson's death. According to published accounts, Johnson stopped drinking in 1972 and underwent a religious conversion, becoming a regular attendee at services of Austin's non-denominational Community Church. Historian
Robert Caro interviewed Johnson as one of his numerous sources while conducting research for
The Years of Lyndon Johnson. According to Caro, he at first considered Johnson to be unreliable, largely as a result of his drinking. Caro said that he considered Johnson more credible in their subsequent encounters, largely because of his sobriety and religious conversion. ==Death and burial==
