While plenty of New Yorkers say they’ll cast their votes for native son Donald Trump in next week’s Republican primary contest, two of Trump’s own kids won’t be among them.

Trump confirmed in a Monday call-in to Fox News his children Ivanka, 34, and Eric, 32, never registered to vote in New York’s closed primary.

Asked if they were “unable to register because of the rules,” Trump replied his children, who are both New York City natives, missed the deadline to register.

“They had a longtime register and they were, you know, unaware of the rules, and they didn’t register in time,” Trump told the hosts of “Fox and Friends.” “So they feel very, very guilty.”

He continued: “They feel very guilty. But it’s fine. I understand that. I think they have to register a year in advance and they didn’t. So Eric and Ivanka, I guess, won’t be voting.”

According to New York’s Board of Elections, new mail-in registrations to vote were due March 30 for the April 19 primary. The deadline to change party enrollment was Oct. 9, 2015 – the earliest change-of-party deadline in the country.
