Mitt Romney congratulated former President George H.W. Bush and his wife, Barbara, on their 67th wedding anniversary Friday.

Romney tweetedHappy Anniversary to George and Barbara Bush — they’re celebrating 67(!) years of marriage today.

George and Barbara Bush married on Jan. 6, 1945.

Romney is friends with the Bush couple and has described them as the most entertaining and delightful people I know and young in heart and mind.

Bush endorsed Romney for the GOP presidential nomination in December. The former president was also a friend of Romney’s father, the late Michigan Gov. George Romney (R).
