Corey Cataldo was heading home from Union Square when another man asked if he was a Trump supporter as the train approached 138th Street-Grand Concourse on Nov. 11, an NYPD spokeswoman said.
Cataldo, 24, said he was and the man responded, “Great, another white Trump supporter,” according to police.
The man then grabbed Cataldo by the neck.
"The next thing I know, I have hands around my neck and I'm being choked," Cataldo told WABC.
"I try to fight him off, and another gentleman comes over, pretends like he's going to help me and says 'get off of him.' He shoves me up against the wall, up against the window."
Cataldo was finally able to fend off the men.
Police later searched the area, but did not find the 6-foot, 190-pound man suspected of choking him, the spokeswoman added.
Cataldo, who reportedly works as an electrician, suffered pain to his left shoulder, police said.
