Convinced that the New Yorker publishes only depressing fiction, Homeland Security missed the monsters landing in Manhattan. The administration got involved when their Russian counterparts cited a credible report from The Onion. But, it was too late. Soon monsters were cavorting with city rats. If you think the aliens were big before, OMG. Hybrids the size of Teslas literally popped from the sewer grates.
Fortunately, the White House saw the situation as an opportunity. Democratic mayor plus vermin problem equals election year coup. It might have worked, except the whole thing was a set up. The rat-monsters wore MAGA hats.
