Fresh from his 40-second demolition of Donald ‘Cowboy’ Cerrone at the weekend, Conor McGregor has dipped his toe into US politics describing Donald Trump as a “phenomenal president.”

McGregor was responding to a tweet from the US president on Martin Luther King Jr. Day where Trump trumpeted his administration’s achievements.

“Phenomenal President,” tweeted McGregor, adding that Trump was “quite possibly” the greatest US commander-in-chief, using a goat emoji to make his point.

“Most certainly one of them anyway, as he sits atop the shoulders of many amazing giants that came before him.

“No easy feet [sic]. Early stages of term also. Incredible.

“Congrats and Happy Martin Luther King Jr. Day America.”

McGregor’s post has had over 13,000 retweets and has been provoking plenty of comment.

“It is hard for me to believe that you published this tweet,” wrote Daniel Reed. “I thought you were trying to win back your Irish fanbase, not alienate them.”

Founder and co-chairman of @TrumpStudents Ryan Fournier was more effusive, tweeting: “You’re not wrong! Trump’s killing it, and so are you!”, while user Stonewall Jackson wondered if McGregor’s support might have an effect on voting intentions in the 2020 election.

“Quite the endorsement for a country with 33 million Irish citizens.”

McGregor’s positive assessment of Trump’s presidency hasn’t always been shared by other prominent athletes.

After helping the US women’s national team win the Women’s World Cup in France last year, Megan Rapinoe challenged Trump to start showing he cares for every single American, saying his message is excluding groups of Americans.

“Your message is excluding people. You’re excluding me, you’re excluding people that look like me, you’re excluding people of color, you’re excluding Americans that maybe support you,” said Rapinoe in an interview with CNN’s Anderson Cooper.
