The hashtag was trending on Friday morning, the president’s 73rd birthday. He started it off by doing an early morning interview on Fox & Friends.
The hashtag appears to have been started by Andy Lassner, the executive producer of the Ellen DeGeneres Show in a tweet where he called on his followers to celebrate the president’s birthday by using the hashtag, according to HuffPost.
In the tweet, Lassner says he was “sure this would mean a lot to patriot like Donald Trump.”
A few hours later Lassner posted a screenshot of #JohnMcCainDay trending on Twitter.
The hashtag caught on, with a lot of people using it to mock Trump.
I refuse to celebrate a draft dodger today. Instead today will be #JohnMcCainDay.— Vanessa Doesn't G.A.F. (@MsVanessainDC) June 14, 2019
