 I'm 7 News meteorologist Mark Pena in the First Alert Weather Center. 92 degrees outside of our studios. You're listening to WTOP, Washington's news, traffic and weather station. WTOP News. Facts matter. Good evening, everyone. I'm Diane Roberts. Coming up, President Biden delivers remarks from the White House on the shooting earlier. We must unite as one nation. And we're expected to hear from President Biden from the Oval Office in just a few minutes. It is 8 o'clock.
