'Why Booker’s campaign never really took off': On Monday, New Jersey Sen. Cory Booker dropped out of the presidential race.

Doff your cap:

A Granbury, Texas, man who bravely jumped into action last month by gunning down an active shooter at a church has received the state's highest civilian honor.

Texas Gov. Greg Abbott presented Jack Wilson with the Medal of Courage Monday morning for stopping \"a gunman in a deadly shooting at a church in North Texas.\"

Wilson, 71, is a former reserve deputy sheriff who was at the West Freeway Church of Christ in Fort Worth on Dec. 29, when Keith Thomas Kinnunen opened fire during a service.

\"I don't see myself as a hero,\" Wilson told reporters after the shooting. \"I see myself as doing what needed to be done to take out the evil threat.\"
