The son of a woman killed on 9/11 who slammed Rep. Ilhan Omar at the annual Ground Zero memorial service over her comments related to the terror attacks said that her remarks “tore my heart apart.”

Nicholas Haros Jr. told Fox News’ Sean Hannity late Wednesday that he “doesn’t remember” where he was when he first heard that Omar described the Sept. 11, 2001, attacks as “some people did something.”

“But,” he said, “it tore my heart apart and it tore my mom’s heart apart with the thought that such a great loss, the individuals could be so insensitively expressed and that hurt.”

Haros, whose mom, Frances Haros, was killed at the age of 76 while working in the south tower of the World Trade Center as a receptionist on 9/11, blasted the Democratic Minnesota congresswoman for her comments earlier Wednesday after reading the names of the dead at the solemn ceremony.

“Madam, objectively speaking, we know who and what was done. There is no uncertainty about that. Why your confusion?” said Haros, wearing a shirt with Omar’s infamous words emblazoned on it.

“On that day, 19 Islamic terrorist members of al Qaeda killed over 3,000 people and caused billions of dollars in economic damage. Is that clear?” said Haros during the televised ceremony.

Omar made the notorious comment last March during a banquet held by the Council on American-Islamic Relations in California.

The former Somali refugee said the group “was founded after 9/11, because they recognized that some people did something and that all of us were starting to lose access to our civil liberties.”

In his interview with Hannity, Haros said: “I am a victim’s son and I decided to take 9/11 as my one day of perhaps credible standing, which many people have told it represented their views.”

Haros did note that he has received some hate mail over his comments during the solemn ceremony.

He said: “Maybe the worst thing that was said about me today was that I was a cranky old man with a bad haircut.”
