Nixon's public image never fully recovered, but he still garnered some approval from Republicans as he frequently defended his legacy. He remained as a consultant to later Presidents, and to other people in government and the media especially to British journalist David Frost. His memoirs are considered important readings. His work in negotiating with China in the early 1970s was praised for improving relations between his country and theirs. Nixon died of a stroke in 1994, ten months after his wife Pat died. Not being able to defend his legacy any longer, his overall approval rating fell, and most everyone today acknowledges his wrongdoings related to Watergate. The house where he was born is now part of the Richard M. Nixon Presidential Library and Museum. He was buried at the library.
