UFC Champion Conor McGregor praised President Trump Monday on social media saying he is a phenomenal president and quite possibly the greatest of all time.

McGregor replied to Trump’s tweet which pointed out it was the anniversary of being sworn in as president three years ago, and it fell on Martin Luther King Jr day.

“It was exactly three years ago today, January 20, 2017, that I was sworn into office. So appropriate that today is also MLK jr DAY. African-American Unemployment is the LOWEST in the history of our Country, by far. Also, best Poverty, Youth, and Employment numbers, ever. Great!” tweeted President Trump.

“Phenomenal President. Quite possibly the USA [goat],” tweeted McGregor. “Most certainly one of them anyway, as he sits atop the shoulders of many amazing giants that came before him. No easy feet. Early stages of term also. Incredible. Congrats and Happy Martin Luther King Jr. day America”

His tweet included a goat emoji, which stands for “greatest of all time.”

McGregor defeated Donald Cerrone Saturday night in Los Vegas, by knocking out Cerrone in 40 seconds.
