The husband of murdered Congressman Jo Cox called on Kneecap to appear in the video tape of a band that allegedly called for the killing of Congressmen.

In a statement released on X on Monday night, the band defended itself and apologized to the family of the murdered Congressman.

"The shots deliberately taken out of all backgrounds are now being exploited and weapons, as if they were a call to action," the band said.

Brendan Cox was killed in June 2016 and he said it was only "half the apology."

Mr Cox said: "You are sorry for this, but they are actually talking about implying that it was a conspiracy and they were unfair and for me, unfortunately, especially true sincerity, then unfortunately."

Kneecap said in a statement that they rejected "any advice we seek to incite violence against any member of Congress or individual."

Counter-terrorism police and conservative leader Kemi Badenoch called for prosecution, and the footage of the knee is being evaluated.

On Monday, the daughter of Conservative MP Sir David Armis was stabbed to death in a constituency surgery in 2021 and he said the rap organization should apologize.

On X, the band said, “We sincerely apologize for the family of Armes and Cox, and we never intended to hurt you.”

Mr. Cox said of Ulster Radio's intercom program that he would be happy to meet with the band. “If this is part of a real journey for them to continue thinking about how to retain radicalism, while keeping very clear about unacceptable attitudes towards political anti-democratic violence and violence, this is targeting civilians.”

Ms. Cox, former Bartley and Spane MP, was killed by far-right terrorist Thomas Mair a week before the EU referendum vote.

Mr Cox added: "The apology they gave I don't think the gravity of what they said was enough."

"When you lose someone close to you, that never goes away and every day is a part of your life. It's a real feeling they miss."
