the former US presidents George W. Bush and Bill Clinton got engaged in a light-hearted "war of words" on their social media accounts.
The 68-year-old 42nd US President took it to his Twitter account to say "Received my copy of #41 by #43, George W. Bush. Touching tribute! #HowAreYouSTILLNotOnTwitter #PresidentialTweeters," ABC News reported.
The 43rd US President Bush, who lacks a Twitter presence and is a regular Instagram user, took it to his Instagram account to respond "Thanks, 42! Hope you like the book about your pal, #41. #HowAreYouSTILLNotOnInstagram #PresidentialGrammers #BrotherFromAnotherMothe."
A spokesman for Bush confirmed that Bush may not always be the one typing out every caption, but his posts are very much his own.
