It was another deadly Independence Day weekend as at least 15 people were killed in a spate of shootings across the U.S. In Philadelphia, an AR-15-toting gunman in a bulletproof vest shot and killed five people and injured two boys in an apparently random mass shooting Monday. In Fort Worth, Texas, an armed attack following Independence Day festivities claimed another three lives. These came after two people were killed and at least 28 injured, including many children, by gunfire at a Baltimore block party. At least five people were shot dead across Chicago over the holiday weekend.

During a speech at the National Education Association on Tuesday, President Biden again called on Congress to pass stricter gun control legislation.

President Joe Biden: “Arming teachers is not the answer. Arming teachers is not the answer. Banning assault weapons and high-capacity magazines, extensive background checks, they’re part of the answer.”
