Note 2 things:
1. While the article does tell us why he needed to leave Venezuela, it doesn’t tell us why he NEEDED to come all the way to the United States.
2. At least TWO of the countries that he passed through have gay marriage (Colombia and Mexico) - why didn’t he apply in either of those countries, particularly Colombia as he is required to do per International Law (first safe country a ‘refugee’ arrives in).
We all know the answers above, but too bad for him - should have followed UN Law, as he’d be living safely in Colombia, rather than being imprisoned in El Salvador.
Likely he applied via CBP-1 app while still in VNZ.
