READ: Text messages Charlie Kirk's suspected shooter sent before arrest

What they are saying: "Why did I do it? I had enough of his hatred," the suspected shooter, 22-year-old Tyler Robinson, wrote to his roommate.

• "Some hate can't be negotiated out."
• According to the messages, Robinson allegedly confirmed he had been planning the shooting for a "bit over a week," and apologized for involving his roommate, whom prosecutors say he was in a romantic relationship with.
• Robinson repeatedly refers to his roommate as his "love," and then encourages them to delete the exchange.

Driving the news: Utah County Attorney Jeff Gray announced Tuesday that his office would be seeking the death penalty in Robinson's case.

• Robinson is facing seven charges, including murder, weapons offenses, obstruction of justice and witness tampering.

• Prosecutors said Robinson will continue to be held without bail in the county jail, and acknowledged the federal government may bring additional charges against him.
• The Justice Department did not immediately respond to Axios' request for comment.

Zoom in: Police were already investigating Kirk's views on gender ideology as a factor in Robinson's motive prior to releasing the charging documents, as Axios' Marc Caputo previously reported.
