The door to America is wide open.
Thousands of migrants are flowing across the US border in Arizona every day — literally through open floodgates that have made the Tucson post the busiest point of illegal entry into the country, The Post has learned.
US officials have inexplicably welded open 114 massive gates along the Arizona border to allow water to flow freely during the annual monsoon season and for the migration of an endangered species of antelope, officials said.
But the move is also letting an average of 1,400 migrants from as far away as China casually walk into the country daily — with overwhelmed and outnumbered border agents practically helpless to stop them.
“We thought the agents were going to tell us something,” one Ecuadorean migrant said. “But we just walked in.”
