Acting Homeland Security Secretary Kevin McAleenan responded to a report Tuesday that an initiative focused on targeted violence and terrorism prevention has about a quarter of the staff and an eighth of the budget of a similar program in the Obama administration. "We need to invest more — no question," McAleenan said Tuesday on "CBS This Morning."

"I've asked Congress for an out-of-cycle budget request to help bolster it and increase our reach and capability. But it doesn't cover the level and scope of effort across the Department of Homeland Security enterprise," McAleenan said, adding the Secret Service reaches out to communities about what threat indicators to look out for and the department provides active shooter training to cities around the country.

There have been more than 250 mass shootings so far this year in the U.S., more than the number of days in the year thus far. At least 31 people were killed and scores were hurt in two mass shootings last weekend in El Paso, Texas, and Dayton, Ohio.
