According to Fox News:
Puerto Rico's governor announced that the U.S. territory has overwhelmingly chosen statehood in a nonbinding referendum Sunday held amid a deep economic crisis that has sparked an exodus of islanders to the U.S. mainland.
Nearly half a million votes were cast for statehood, more than 7,600 for free association/independence and nearly 6,700 for independence, according to preliminary results. The participation rate was just 23 percent with roughly 2.26 million registered voters, leading opponents to question the validity of a vote that several parties had boycotted.

Some of that is minor case of Trump Derangement Syndrome in that you have to get past Congress first

In the case of PR, given that it is PR, I could see the situation going to the Supreme Court regardless who's prez or who's running congress, so essentially you'll have to get past all three branches.
