LSU Tigers head coach Ed Orgeron says the team's trip to the White House was a PHENOMENAL experience ... telling TMZ Sports POTUS is an awesome host!!!
The national champs spent the day at 1600 Penn in Washington D.C. ... and there was a ton of action -- #45 joking about being impeached, players doing the "Get The Gat" challenge, and Coach O's name getting butchered during introductions.
We spoke with coach out in the nation's capital about the visit ... and he couldn't have been happier about how it went down.
"It was phenomenal. President Trump was a gracious host, spent a lot of time with us," Orgeron said.
"[He's] very knowledgeable about football. It was one of the best experiences we've ever had. What a great experience for our football team."
O says he and his wife even got a personal tour of the White House!!!
"I felt really good about being at the White House ... Everything was A+ today."
We also spoke with some of the players, and they backed up O's review, saying the trip was "amazing!"
Some of the guys also had a message for Clemson ... and you're gonna wanna check that out!!!
