On September 10, 2025, commenting on the killing of Charlie Kirk, Dowd said on-air, "He's been one of the most divisive, especially divisive younger figures in this, who is constantly sort of pushing this sort of hate speech or sort of aimed at certain groups. And I always go back to, hateful thoughts lead to hateful words, which then lead to hateful actions. And I think that is the environment we are in. You can't stop with these sort of awful thoughts you have and then saying these awful words and not expect awful actions to take place. And that's the unfortunate environment we are in." Dowd also speculated that the shooter may have been a supporter, stating "We don’t know if this was a supporter shooting their gun off in celebration. So we have no idea about this".[22]
Later that day, MSNBC president Rebecca Kutler denounced Dowd's comments, saying, "During our breaking news coverage of the shooting of Charlie Kirk, Matthew Dowd made comments that were inappropriate, insensitive, and unacceptable. We apologize for his statements, as has he. There is no place for violence in America, political or otherwise."[23][24] That evening, Dowd was fired from MSNBC.[25]
