One of Woods's golfing partners noticed, too. "Love people who are great under pressure," President Trump tweeted. "What a fantastic life comeback for a really great guy!"
Former president Barack Obama, called Woods's win "a testament to excellence, grit and determination."
Other golfers were moved, too. Even Woods's former adversary, Phil Mickelson, noticed. "What a great moment for the game of golf. I'm so impressed by Tiger Woods' incredible performance, and I'm so happy for him to capture another Green Jacket," he tweeted. "Truly a special day that will go down in history."
Part of what made it special was the interaction between Woods and his kids and afterward he spoke of having his daughter Sam and son Charlie with him, just as they were all those years he was injured.
"It means the world to me. their love and their support is — I just can't say enough about how much it meant to me during my struggles, just the infectiousness of happiness as I was going through a tough time physically when I just couldn't move. Now, to have them see their pops win, just like my pops saw me win here, is pretty special."
Other greats in their sports, including Serena Williams, Steph Curry and Tom Brady, reacted to the stunning win, and Twitter officials noted that there were more than 1.4 million tweets about Woods and more than 1.8 million about the Masters.
