Nixon and Prince Philip

 An article about a Nixon and Prince Philip connection: 

Throughout his decades in public life, Prince Philip was known for putting his royal foot in his mouth with occasional off-the-cuff remarks that could be embarrassing. But his faux pas at a White House dinner with President Richard Nixon in 1969 was enough for Philip to actually lose sleep.

In a handwritten note to the president uncovered by archivists at the Richard Nixon Presidential Library and Museum in Yorba Linda, California, the Duke of Edinburgh wrote to “humbly apologize” for failing to toast the president’s health as dictated by protocol during a “stag” dinner in his honor.

The dinner came a day after Nixon delivered his famous “silent majority” speech in which he implored a national audience to unite behind the continuing war in Vietnam until his administration could achieve “peace with honor.” Byron said top aide H.R. Haldeman, who later went to prison for his involvement in the Watergate scandal, noted in his diary how absolutely joyful the president was that night, given that his address had been positively received.
