Ex-Trump adviser Michael Flynn endorses Fernando Mateo for mayor

Former Trump national security adviser Michael Flynn is endorsing Fernando Mateo in the Republican primary for mayor.

Restaurateur and bodega worker advocate Mateo is the underdog against his better-known GOP rival, Guardian Angels founder Curtis Sliwa. Flynn is not a New Yorker and his backing of Mateo raises the specter that former President Donald Trump, a Big Apple native, might get involved in the race on Mateo’s behalf, a campaign insider speculated.
