It was reported Monday morning on Fox News, following a weekend revelation by Conservative Review, that both Eric and Ivanka Trump failed to register in time to vote for their dad in the Empire State's April 19 primary.

“Ivanka and Eric Trump are unable to register because of the rules,” the real estate mogul was told on "Fox & Friends." “Are the rules in New York unfair as well?”

"No. They had a long time to register, and they were unaware of the rules, and they didn't register in time,” Trump responded. "So they feel very, very guilty.

“I think they have to register a year in advance, and they didn't,” he added, “so Eric and Ivanka, I guess, won’t be voting."
