Late-night television host Jimmy Kimmel has the most-watched video on YouTube right now -- over 3 million views in less than a day. Kimmel is known for making jokes, but instead, he’s talking about something serious. The video is about 10 minutes long. He was talking to his audience about the mass shooting Sunday night at a concert in Las Vegas, Nevada. Fifty-nine people were killed and more than 500 others were hurt. Kimmel grew up in Las Vegas. He was close to crying as he spoke during the “Jimmy Kimmel Live!” show on Monday. “We have children without parents and fathers without sons, mothers without daughters,” Kimmel said. Kimmel told the audience that the United States is not doing enough to control access to guns.
