"As we dug into the data it appears someone has erroneously posted a number of scores on behalf of the GHIN user. We are taking corrective action to remove the scores and partnering with our allied golf associations and their member clubs to determine the origin of the issue."
The USGA removed the four scores in the 100s and the 68 - although the organisation did not make clear whether the 68 was part of the hack.
The round was first noticed by sportswriter Leif Skodnick.
The score was particularly striking because it was shot on a course with a 75.3 rating, making it a really difficult track.
For context, Bethpage Black – where Woods and the rest of the world's best golfers are currently playing at the PGA Championship – has a 77.5 rating.
However, it is worth noting that Trump did post a 68 in November 2017 to the same platform, only to then delete it without explanation.
The president has also been accused several times of not adhering to the proper rules of the game and having a fake handicap (supposedly 1.8), which was outlined in the book Commander in Cheat by Rick Reilly.
Earlier this month, Trump awarded Woods with the Presidential Medal of Freedom – America's highest civilian honour – describing the Masters champ as a "true legend".
